我正在开发一个应用程序,我只需要一个带广播接收器的外部应用程序。这是我的代码:

APP1:

Intent intent = new Intent();
intent.setAction("com.blabla.myaction");
intent.putExtra("extra", "test");
sendBroadcast(intent);

app2(带接收器的那个):

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.test.test" >

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme">
<receiver
    android:name=".myReceiver">
    <intent-filter>
        <action android:name="com.blabla.myaction" />
    </intent-filter>
</receiver>
</manifest>

public class myReceiver extends BroadcastReceiver {

private Context mContext;

public static final String ACTION = "com.blabla.myaction";

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

    if (ACTION.equals(intent.getAction())) {
        Log.e("lala", "received");

        String extra = intent.getStringExtra("extra");

        if (packageName != null) {
            Log.e("lala", extra);
        }
    }
}

有了这个,我没有得到“收到”的日志,也没有得到额外的。为什么呢?

您“接收申请必须至少启动一次。
