AndroidDeadException是一种系统级异常,通常是由于应用程序在后台运行时被杀死而引起的。在Knox和Samsung设备上,这个异常可能会出现在Android 12版本上。为了解决这个问题,可以遵循以下步骤:
//定义前台服务 public class MyForegroundService extends Service { @Override public int onStartCommand(Intent intent, int flags, int startId) { Notification notification = new NotificationCompat.Builder(this, CHANNEL_ID) .setContentTitle("My App Name") .setContentText("Running in background") .setSmallIcon(R.drawable.ic_notification) .build(); startForeground(FOREGROUND_SERVICE_ID, notification); return START_STICKY; } }
//启动前台服务 Intent serviceIntent = new Intent(context, MyForegroundService.class); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { context.startForegroundService(serviceIntent); } else { context.startService(serviceIntent); }
//在Application类中注册UncaughtExceptionHandler public class MyApplication extends Application { @Override public void onCreate() { super.onCreate(); Thread.setDefaultUncaughtExceptionHandler(new MyUncaughtExceptionHandler()); } }
//定义UncaughtExceptionHandler public class MyUncaughtExceptionHandler implements Thread.UncaughtExceptionHandler { @Override public void uncaughtException(Thread t, Throwable e) { if (e instanceof AndroidDeadException) { //重启应用程序 Intent intent = getBaseContext().getPackageManager() .getLaunchIntentForPackage(getBaseContext().getPackageName()); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent); Process.killProcess(Process.myPid()); System.exit(0); } } }
通过上述解决方法,可以有效避免AndroidDeadException异常的发生。
