Question

我正在尝试从bc_from广播到bc_to 如果我在Activity bc_to中使用它可以正常工作：

registerReceiver(receiver, filter);

如果我在Manifest中定义接收器，它就不起作用
我从文件中了解到，自26年以来这可能是不可能的所以我正在寻找能够达到活动bc_to的任何解决方案，即使它没有运行。

由于

// package com.yotam17.ori.bc_from;
public class MainActivity extends AppCompatActivity {

    private static final String BC_ACTION = "com.yotam17.ori.bc.Broadcast";

    private void send() {
        Intent intent = new Intent(BC_ACTION);
        intent.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES);
        sendBroadcast(intent);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        send();
    }
}

bc_from的代码包含Manifest和两个clases：

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

    <receiver android:name="com.yotam17.ori.bc_to.MyReceiver" >
        <intent-filter>
            <action android:name="com.yotam17.ori.bc.Broadcast"/>
        </intent-filter>
    </receiver>

    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:theme="@style/AppTheme.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

// package com.yotam17.ori.bc_to;
public class MainActivity extends AppCompatActivity {

    private static final String BC_ACTION = "com.yotam17.ori.bc.Broadcast";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Register MyReceiver
        IntentFilter filter = new IntentFilter(BC_ACTION);
        MyReceiver receiver = new MyReceiver();
        registerReceiver(receiver, filter); //<<<<<< Does not work w/o this
    }
}

public class MyReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        Toast.makeText(context, "Got it!!!" , Toast.LENGTH_SHORT).show();
    }
}

谢谢！
setComponent（）解决了它我以前从未使用过setComponent（），但是找到了一个详细的例子here。

为了使它成为一个工作示例 - 这里是修改后的send（）代码：

private void send() {
    Intent intent = new Intent(BC_ACTION);
    intent.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES);
    intent.setComponent(new ComponentName("com.yotam17.ori.bc_to","com.yotam17.ori.bc_to.MyReceiver"));
    sendBroadcast(intent);
}

从app1广播到app2
