android9.0 apk静默安装

热度:82   发布时间:2024-02-27 06:55:07

封装一个类,调用系统的的方法进行静默安装

public class PackageManagerCompatP {private static final String TAG = PackageManagerCompatP.class.getSimpleName();@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)public static void install(Context context, String apkFilePath, PackageManager packageManager) {File apkFile = new File(apkFilePath);PackageInstaller packageInstaller = packageManager.getPackageInstaller();PackageInstaller.SessionParams sessionParams = new PackageInstaller.SessionParams(PackageInstaller.SessionParams.MODE_FULL_INSTALL);sessionParams.setSize(apkFile.length());int sessionId = createSession(packageInstaller, sessionParams);if (sessionId != -1) {boolean copySuccess = copyInstallFile(packageInstaller, sessionId, apkFilePath);if (copySuccess) {execInstallCommand(context, packageInstaller, sessionId);}}}@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)private static int createSession(PackageInstaller packageInstaller,PackageInstaller.SessionParams sessionParams) {int sessionId = -1;try {sessionId = packageInstaller.createSession(sessionParams);} catch (IOException e) {e.printStackTrace();}return sessionId;}@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)private static boolean copyInstallFile(PackageInstaller packageInstaller,int sessionId, String apkFilePath) {InputStream in = null;OutputStream out = null;PackageInstaller.Session session = null;boolean success = false;try {File apkFile = new File(apkFilePath);session = packageInstaller.openSession(sessionId);out = session.openWrite("base.apk", 0, apkFile.length());in = new FileInputStream(apkFile);int total = 0, c;byte[] buffer = new byte[65536];while ((c = in.read(buffer)) != -1) {total += c;out.write(buffer, 0, c);}session.fsync(out);success = true;} catch (IOException e) {e.printStackTrace();} finally {closeQuietly(out);closeQuietly(in);closeQuietly(session);}return success;}@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)private static void execInstallCommand(Context context, PackageInstaller packageInstaller, int sessionId) {PackageInstaller.Session session = null;try {session = packageInstaller.openSession(sessionId);Intent intent = new Intent(context, InstallResultReceiver.class);PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 1, intent, PendingIntent.FLAG_UPDATE_CURRENT);session.commit(pendingIntent.getIntentSender());} catch (IOException e) {e.printStackTrace();} finally {closeQuietly(session);}}private static void closeQuietly(Closeable c) {if (c != null) {try {c.close();} catch (IOException ignored) {ignored.printStackTrace();}}}
}

调用的话很简单

PackageManagerCompatP.install(getApplicationContext(),"sdcard/test.apk",getPackageManager());

需要权限

  <uses-permission android:name="android.permission.INSTALL_PACKAGES" />

测试了一下,可以不用添加

android:sharedUserId="android.uid.system"

为了让app有权限,可以让app进行系统签名,或者可以修改PermissionManagerService.java文件

                 if (DEBUG_PERMISSIONS) {Slog.i(TAG, "Granting permission " + perm + " to package " + pkg.packageName);}
+				
+				//add by jueme for apk permission at 20200915
+				if(pkg.packageName.equals("com.jueme.android.autoinstall")){
+					Log.i(TAG, "com.jueme.android.autoinstall");
+					grant = GRANT_INSTALL;
+				}
+				//add end +if (grant != GRANT_DENIED) {if (!ps.isSystem() && ps.areInstallPermissionsFixed()) {

grant = GRANT_INSTALL给app所有的权限,只要app申请了任何的权限都默认打开。

还有一个问题就是客户要求安装之后要自启动app,可以使用广播来监听

public class InstallResultReceiver extends BroadcastReceiver {private static final String TAG = "InstallResultReceiver";@Overridepublic void onReceive(Context context, Intent intent) {Log.d(TAG, "onReceive: "+intent.getIntExtra(PackageInstaller.EXTRA_STATUS,PackageInstaller.STATUS_FAILURE));if (intent != null) {final int status = intent.getIntExtra(PackageInstaller.EXTRA_STATUS,PackageInstaller.STATUS_FAILURE);if (status == PackageInstaller.STATUS_SUCCESS) {} else {}}}
}
 <receiver android:name=".InstallResultReceiver"android:enabled="true"android:exported="true"><intent-filter><action android:name="android.content.pm.extra.STATUS"/></intent-filter></receiver>

监听其他app安装是没有问题的,可以收到广播。但是当进行自身安装的会监听不到广播,因为app安装完成之后就退出去了,这时想要在app里面监听是实现不了的。想了一个办法,把framework层修改了,找到发广播的地方PackageInstallerService.java。

static class PackageInstallObserverAdapter extends PackageInstallObserver {...@Overridepublic void onPackageInstalled(String basePackageName, int returnCode, String msg,Bundle extras) {if (PackageManager.INSTALL_SUCCEEDED == returnCode && mShowNotification) {boolean update = (extras != null) && extras.getBoolean(Intent.EXTRA_REPLACING);Notification notification = buildSuccessNotification(mContext,mContext.getResources().getString(update ? R.string.package_updated_device_owner :R.string.package_installed_device_owner),basePackageName,mUserId);if (notification != null) {NotificationManager notificationManager = (NotificationManager)mContext.getSystemService(Context.NOTIFICATION_SERVICE);notificationManager.notify(basePackageName,SystemMessage.NOTE_PACKAGE_STATE,notification);}}//add by jueme for start customer app at 20200927if(basePackageName.equals("com.jueme.android.autoinstall")){new Thread(new Runnable(){@Overridepublic void run(){try {Slog.d(TAG,"onPackageInstalled basePackageName "+basePackageName+" returnCode "+returnCode+" msg "+msg);Thread.sleep(500);Intent intent = new Intent();intent.setClassName("com.jueme.android.autoinstall","com.jueme.android.autoinstall.MainActivity");intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);mContext.startActivity(intent);} catch (Exception e) {Slog.e(TAG,"onPackageInstalled Exception "+e.toString());}}}).start();}//add endfinal Intent fillIn = new Intent();fillIn.putExtra(PackageInstaller.EXTRA_PACKAGE_NAME, basePackageName);fillIn.putExtra(PackageInstaller.EXTRA_SESSION_ID, mSessionId);fillIn.putExtra(PackageInstaller.EXTRA_STATUS,PackageManager.installStatusToPublicStatus(returnCode));fillIn.putExtra(PackageInstaller.EXTRA_STATUS_MESSAGE,PackageManager.installStatusToString(returnCode, msg));fillIn.putExtra(PackageInstaller.EXTRA_LEGACY_STATUS, returnCode);if (extras != null) {final String existing = extras.getString(PackageManager.EXTRA_FAILURE_EXISTING_PACKAGE);if (!TextUtils.isEmpty(existing)) {fillIn.putExtra(PackageInstaller.EXTRA_OTHER_PACKAGE_NAME, existing);}}try {mTarget.sendIntent(mContext, 0, fillIn, null, null);} catch (SendIntentException ignored) {}}...
}

这里睡500ms是因为在测试过程中发现会概率性启动不了app,原因就是在还没有完全安装好就调用了启动的方法,加了延时之后就没发现问题了。
