APK的更新、安装、隐藏、解除隐藏

2023-09-26 掘金 457 推广

一、用户安装的apk发生更新

public void registerReceiver(Context context) {
        Slog.d("PMSdddd", "systemReady1");
        IntentFilter filter = new IntentFilter();
        filter.addAction(Intent.ACTION_PACKAGE_ADDED);
        filter.addAction(Intent.ACTION_PACKAGE_CHANGED);
        filter.addAction(Intent.ACTION_PACKAGE_REPLACED);
        filter.addAction(Intent.ACTION_PACKAGE_REMOVED);
        filter.addDataScheme("package");
        BroadcastReceiver packgeMonitorReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                final String action = intent.getAction();
                final String packageName =
intent.getData().getSchemeSpecificPart();
                final boolean replacing =
intent.getBooleanExtra(Intent.EXTRA_REPLACING, false);
                final boolean dataRemoved =
intent.getBooleanExtra(Intent.EXTRA_DATA_REMOVED, false);

                Slog.d("PMSdddd", "action: " + action + " packageName:"
+ packageName + "  replacing:" + replacing
                        + "  dataRemoved:" + dataRemoved);
            }
        };
        context.registerReceiver(packgeMonitorReceiver, filter);
    }

第1步，新安装apk

adb install apk

Line 52701: 02-01 21:26:23.213  1727  1727 D PMSdddd : action: android.intent.action.PACKAGE_ADDED  packageName:com.adobe.reader  replacing:false  dataRemoved:false

第2步，hide此 apk

adb shell pm hide apk

Line 53895: 02-01 21:28:22.043  1727  1727 D PMSdddd : action: android.intent.action.PACKAGE_REMOVED  packageName:com.adobe.reader  replacing:false  dataRemoved:false

第3步，adb install更新
adb install -r apk

Line 54477: 02-01 21:29:41.550  1727  1727 D PMSdddd : action: android.intent.action.PACKAGE_REMOVED  packageName:com.adobe.reader  replacing:true  dataRemoved:false


Line 54512: 02-01 21:29:41.648  1727  1727 D PMSdddd : action: android.intent.action.PACKAGE_ADDED  packageName:com.adobe.reader  replacing:true  dataRemoved:false

第4步，再unhide此apk

adb shell pm unhide apk

Line 55640: 02-01 21:32:25.651  1727  1727 D PMSdddd : action: android.intent.action.PACKAGE_ADDED  packageName:com.adobe.reader  replacing:false  dataRemoved:false

第5步，adb uninstall 卸载apk

Line 61310: 02-01 21:52:36.395  1727  1727 D PMSdddd : action: android.intent.action.PACKAGE_REMOVED  packageName:com.adobe.reader  replacing:false  dataRemoved:true

总结：

hide命令：系统会发送广播 android.intent.action.PACKAGE_REMOVED，data数据并不会删除
unhide命令：系统会发送广播android.intent.action.PACKAGE_ADDED，data数据不会删除

更新apk时：

系统先发送广播 android.intent.action.PACKAGE_REMOVED，intent.getBooleanExtra(Intent.EXTRA_REPLACING, false) 获取的值为true

系统随后发送广播android.intent.action.PACKAGE_ADDED，intent.getBooleanExtra(Intent.EXTRA_REPLACING, false) 获取的值也为true

卸载apk时：

系统发送广播 android.intent.action.PACKAGE_REMOVED，intent.getBooleanExtra(Intent.EXTRA_DATA_REMOVED, false)获取的值为true

二、系统apk（位于：system/app 目录）发生更新

第1步，预置apk(v1.0)到system/app

adb push apk system/app

再恢复出厂设置
第2步，adb install-r更新apk到v2.0

Line 8118: 02-02 02:55:59.428  1130  1130 D PMSdddd : action: android.intent.action.PACKAGE_REMOVED  packageName:com.example.ddd  replacing:true  dataRemoved:false


Line 8134: 02-02 02:55:59.501  1130  1130 D PMSdddd : action: android.intent.action.PACKAGE_ADDED  packageName:com.example.ddd  replacing:true  dataRemoved:false


Line 8281: 02-02 02:55:59.903  1130  1130 D PMSdddd : action: android.intent.action.PACKAGE_REPLACED  packageName:com.example.ddd  replacing:true  dataRemoved:false

更新后的apk安装在 data/app目录：

    Line 8550: 02-02 05:12:10.806  1132  1228 I PackageManager: Update system package com.example.ddd code path from /system/operator/app/AndroidDemoV1.0.apk to /data/app/~~IYd549AfrGeHUc-lWfY8kg==/com.example.ddd-o9yTi7O1l3Cm3EhqTvf2Rw==; Retain data and using new
    Line 8550: 02-02 05:12:10.806  1132  1228 I PackageManager: Update system package com.example.ddd code path from /system/operator/app/AndroidDemoV1.0.apk to /data/app/~~IYd549AfrGeHUc-lWfY8kg==/com.example.ddd-o9yTi7O1l3Cm3EhqTvf2Rw==; Retain data and using new
    Line 8551: 02-02 05:12:10.808  1132  1228 I PackageManager: Update system package com.example.ddd resource path from /system/operator/app/AndroidDemoV1.0.apk to /data/app/~~IYd549AfrGeHUc-lWfY8kg==/com.example.ddd-o9yTi7O1l3Cm3EhqTvf2Rw==; Retain data and using new
    Line 8551: 02-02 05:12:10.808  1132  1228 I PackageManager: Update system package com.example.ddd resource path from /system/operator/app/AndroidDemoV1.0.apk to /data/app/~~IYd549AfrGeHUc-lWfY8kg==/com.example.ddd-o9yTi7O1l3Cm3EhqTvf2Rw==; Retain data and using new

第3步，Settings“应用信息”界面无法卸载，没有卸载按钮（打开、停用、强行停止三个按钮）

总结：

系统apk发生更新时，系统依次发送广播：action: android.intent.action.PACKAGE_REMOVED、action: android.intent.action.PACKAGE_ADDED、action: android.intent.action.PACKAGE_REPLACED

且 intent.getBooleanExtra(Intent.EXTRA_REPLACING, false) 获取的值为true

Android 监听多用户切换，隐藏和禁用指定Apk

IntentFilter filter = new IntentFilter();
        filter.addAction(Intent.ACTION_USER_SWITCHED);
        filter.addAction(Intent.ACTION_USER_ADDED);
        BroadcastReceiver mUserSwitchedReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                final String action = intent.getAction();
                final int userId = intent.getIntExtra(Intent.EXTRA_USER_HANDLE, UserHandle.USER_NULL);
                if (userId == UserHandle.USER_NULL) {
                    Slog.e("PMSdddd", "received an invalid EXTRA_USER_HANDLE");
                    return;
                }
                if (Intent.ACTION_USER_SWITCHED.equals(action) && userId > 0) {
                    Slog.d("PMSdddd", "User switched to userId " + userId);
                    AsyncTask.execute(new Runnable() {
                        @Override
                        public void run() {
                            Slog.d("PMSdddd", "install start11");
                            Sbbbbbbbbbbb.hideOtherBrandAppWhenUserSwitched();
                        }
                    });
                } else if (Intent.ACTION_USER_ADDED.equals(action) && userId > 0) {
                    Slog.d("PMSdddd", "Added User  userId " + userId);
                    AsyncTask.execute(new Runnable() {
                        @Override
                        public void run() {
                            Slog.d("PMSdddd", "install start11");
Sbbbbbbbbbbb
.hideOtherBrandAppWhenUserSwitched(); } }); } } }; mContext.registerReceiver(mUserSwitchedReceiver, filter);

是否隐藏和禁用apk

/**
     * only hide app but don't delete user data
     *
     * @param pkgName
     */
    private void hide(String pkgName) {
        final PackageManager pm = mContext.getPackageManager();
        int userId = ActivityManager.getCurrentUser();
        pm.setApplicationHiddenSettingAsUser(pkgName, true, new UserHandle(userId));
        disableApplication(pkgName);
    }

    private void unhide(String pkgName) {
        final PackageManager pm = mContext.getPackageManager();
        int userId = ActivityManager.getCurrentUser();
        pm.setApplicationHiddenSettingAsUser(pkgName, false, new UserHandle(userId));
        enableApplication(pkgName);
    }

    private void disableApplication(String pkgName) {
        final PackageManager pm = mContext.getPackageManager();
        try {
            int state = pm.getApplicationEnabledSetting(pkgName);
            Slog.d(TAG, "disableApplication state: " + state + " pkgName:" + pkgName);
            if (state == PackageManager.COMPONENT_ENABLED_STATE_DISABLED)
                return;
            pm.setApplicationEnabledSetting(pkgName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, 0);
        } catch (IllegalArgumentException exeption) {
            Slog.w(TAG, "disableApplication error:" + exeption.getMessage());
        }
    }

    private void enableApplication(String pkgName) {
        final PackageManager pm = mContext.getPackageManager();
        try {
            int state = pm.getApplicationEnabledSetting(pkgName);
            Slog.d(TAG, "enableApplication state: " + state + " pkgName:" + pkgName);
            if (state == PackageManager.COMPONENT_ENABLED_STATE_ENABLED)
                return;
            pm.setApplicationEnabledSetting(pkgName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, 0);
        } catch (IllegalArgumentException exeption) {
            Slog.w(TAG, "enableApplication error:" + exeption.getMessage());
        }
    }

隐藏的apk或disable的apk，信息保存在 /data/system/users/0/package-restrictions.xml 文件内

apk被hide后，保存的信息：hidden=”true”

apk被disable后，根据 setApplicationEnabledSetting 传入的常量参数不同，enabled= 的值就会不同，如下介绍：

public static final int COMPONENT_ENABLED_STATE_DISABLED = 2;  // disable应用时，若传入此参数，则应用在桌面没有图标，且在设置界面、应用程序列表里面也没有图标 （应用完全隐藏了）

public static final int COMPONENT_ENABLED_STATE_DISABLED_USER = 3;  // disable应用时，若传入此参数，则应用在桌面没有图标，但是在设置界面、应用程序列表里面有图标 (只是桌面图标隐藏了，设置里面仍可以看到图标，用户可以再次enable此应用)

另外：adb shell pm disable-user 应用包名： 相当于传入的参数是 COMPONENT_ENABLED_STATE_DISABLED。

查看手机有哪些应用处于disable状态的方法:

方法1：adb shell pm list packages -d

C:Userszzz>adb shell pm list packages -d
package:com.facebook.services
package:com.google.android.videos
package:com.facebook.appmanager

方法2：adb shell pm dump packages > Desktop/log2.txt

enabled=2 —->表示应用处于disable状态，对应的值：COMPONENT_ENABLED_STATE_DISABLED

查看哪些应用属于系统签名？

方法：adb shell pm dump packages > Desktop/log2.txt

包名为”android”的apk属于平台apk，肯定是系统签名，首先看一下包名为”android”的apk的签名信息：

 Package [android] (ad28bfa):
    userId=1000
    sharedUser=SharedUserSetting{769a3df android.uid.system/1000}
    pkg=Package{6103b22 android}
    codePath=/system/framework/framework-res.apk
    resourcePath=/system/framework/framework-res.apk
    legacyNativeLibraryDir=/system/lib64/framework-res
    primaryCpuAbi=arm64-v8a
    secondaryCpuAbi=null
    versionCode=30 minSdk=30 targetSdk=30
    versionName=11
    splits=[base]
    apkSigningVersion=3
    applicationInfo=ApplicationInfo{6103b22 android}
    flags=[ SYSTEM PERSISTENT ALLOW_BACKUP ]
    privateFlags=[ PRIVATE_FLAG_ACTIVITIES_RESIZE_MODE_RESIZEABLE_VIA_SDK_VERSION ALLOW_AUDIO_PLAYBACK_CAPTURE DEFAULT_TO_DEVICE_PROTECTED_STORAGE DIRECT_BOOT_AWARE PRIVILEGED PRIVATE_FLAG_ALLOW_NATIVE_HEAP_POINTER_TAGGING ]
    forceQueryable=true
    queriesPackages=[]
    dataDir=/data/system
    supportsScreens=[small, medium, large, xlarge, resizeable, anyDensity]
    timeStamp=2021-07-12 23:27:41
    firstInstallTime=2021-07-12 23:27:41
    lastUpdateTime=2021-07-12 23:27:41
    signatures=PackageSignatures{539b9b3 version:3, signatures:[a0521abc], past signatures:[]}
    installPermissionsFixed=true
    pkgFlags=[ SYSTEM PERSISTENT ALLOW_BACKUP ]
    declared permissions:
      android.permission.READ_CONTACTS: prot=dangerous, INSTALLED
      android.permission.WRITE_CONTACTS: prot=dangerous, INSTALLED
      ........

    User 0: ceDataInode=4316 installed=true hidden=false suspended=false distractionFlags=0 stopped=false notLaunched=false enabled=0 instant=false virtual=false
    overlay paths:
      /product/overlay/NavigationBarModeGestural/NavigationBarModeGesturalOverlay.apk

从上面信息可以看到，签名信息：signatures:[a0521abc] ，然后在 log2.txt 文件全局搜索“a0521abc”，可以列出所有系统签名的应用。
