Android 接收不到开机广播，接收不到adb发送的广播

[NullPointerK]

最近在弄一个开机自启动的需求，已经按照一般方法静态注册，写一个接受广播，也将应用安装到系统目录 /system/app，但是就是接收不到广播，也接收不到adb自己发送的广播。哪位大佬能帮帮忙

public class UpdateReceiver extends BroadcastReceiver {
    public static final String TAG = UpdateReceiver.class.getSimpleName();

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        String packageName = intent.getDataString().substring(8);
        Log.i(TAG,"BootReceiver onReceive():接收到Intent.getAction() = "+intent.getAction()+" , 包名 = "+intent.getDataString());

        /**
         * 接收安装广播
         * android.intent.action.PACKAGE_ADDED
         * */
        if (action.equals(Intent.ACTION_PACKAGE_ADDED)) {
            Log.i(TAG,"BootReceiver onReceive():安装了:" + packageName + "包名的程序");

        }

        /**
         * 接收卸载广播
         * android.intent.action.PACKAGE_REMOVED
         * */
        if (action.equals(Intent.ACTION_PACKAGE_REMOVED)) {
            Log.i(TAG,"接收卸载广播");

        }

        /**
         * 接收更新广播
         * android.intent.action.PACKAGE_REPLACED
         * */
        if(action.equals(Intent.ACTION_PACKAGE_REPLACED)){
            Log.i(TAG,"BootReceiver onReceive():更新了:" + packageName + "包名的程序，context.getPackageName()="+context.getPackageName());
            Intent intent2 = new Intent(context, SettingActivity.class);
            intent2.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(intent2);

        }
        /**
         * 接收重启广播
         * android.intent.action.PACKAGE_REPLACED
         * */
        if(action.equals(Intent.ACTION_PACKAGE_RESTARTED)){
            Log.i(TAG,"BootReceiver onReceive():重启了:" + packageName + "包名的程序");
            Intent intent2 = new Intent(context, SettingActivity.class);
            intent2.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(intent2);
        }

        /**
         * 接收开机广播
         * android.intent.action.BOOT_COMPLETED
         * */
        if(action.equals(Intent.ACTION_BOOT_COMPLETED)){
            Log.i(TAG,"BootReceiver onReceive():仪器开机，开启了:" + packageName + "包名的程序");
            Intent intentMainActivity = new Intent(context, SettingActivity.class);
            intentMainActivity.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(intentMainActivity);
        }

    }
}

/**
 * 自启动广播
 */
public class SelfstartingReceiver extends BroadcastReceiver {

    public SelfstartingReceiver() {
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
            Intent i = new Intent(context, MainActivity.class);
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(i);
        }
    }
}
AndroidManifest中注册下
 <receiver
            android:name=".Recevier.SelfstartingReceiver"
            android:enabled="true"
            android:exported="true">
            <intent-filter android:priority="1000">
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>
