Android 屏蔽recent按键 ，Home按键，Recent按键的监听能够用广播，还有开机启动app

屏蔽recent按键:

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

@Override
protected void onPause() {
    super.onPause();
    ActivityManager activityManager = (ActivityManager) getApplicationContext()
            .getSystemService(Context.ACTIVITY_SERVICE);
    activityManager.moveTaskToFront(getTaskId(), 0);
}

开机自启动：

public class BootBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i("selftoactive", intent.getAction());
        if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
            Log.i("selftoactive", intent.getAction());
            Toast.makeText(context, "开机自启动！！！", Toast.LENGTH_SHORT).show();
            Intent intent1 = new Intent(context, FirstActivity.class);
            intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//这个是重点，没有设置这个，app不会启                                                              动，并且开机后有延迟几秒才会收到，开                                                              机发送过来的信号
            context.startActivity(intent1);
        }
    }
}

<receiver android:name="com.lgkj.meicqt.utils.BootBroadcastReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

Home按键，Recent按键的监听能够用广播：Recent按键相似

/**

 */

public class HomeKeyBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        Log.i("homekey1", action);
        if (Intent.ACTION_CLOSE_SYSTEM_DIALOGS.equals(action)) {
            Log.i("homekey1", action);
            String reason = intent.getStringExtra("reason");
            Log.i("homekey1", reason);
            if ("homekey".equals(reason)) {
                //按下home键时的状况下
                //do nothing just 拦截事件
                Log.i("homekey1", "do nothing else xixi~~");
            }
        }
    }
}
