java - 安装特定应用程序后广播接收器获取 Toast

Question

我正在开发 Android 应用程序。首先，我不熟悉 BroadcastReceiver。我需要创建一个应用程序，如果安装应用程序有特定的包，如“com.whatsapp”，广播接收器将显示 Toast

public class PackageAddedReceiver extends BroadcastReceiver {

    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "Package Installed: ", Toast.LENGTH_LONG).show();
    }
}

list

<receiver android:name=".receiver.PackageAddedReceiver" android:label="Package added Receiver">
    <intent-filter>
        <action android:name="android.intent.action.PACKAGE_ADDED" />
        <action android:name="android.intent.action.PACKAGE_REMOVED"/>
        <data android:scheme="package"/>
    </intent-filter>
</receiver>

如何为特定包添加 BroadcastReceiver？

Answer 1

试试这个

public class PackageAddedReceiver extends BroadcastReceiver {

    public void onReceive(Context context, Intent intent) {



        Uri data = intent.getData();
        String mypkg="package:com.pck.name";

        Log.e("DATA",data+"");
        Log.e( "Action: " ,intent.getAction());

        if(mypkg.equals(data.toString())){
            Toast.makeText(context, "Package Installed: ", Toast.LENGTH_LONG).show();
        }else {
            Toast.makeText(context, "not match ", Toast.LENGTH_LONG).show();
        }

    }

list 代码

 <receiver android:name=".PackageAddedReceiver">
        <intent-filter>
            <action android:name="android.intent.action.PACKAGE_INSTALL" />
            <action android:name="android.intent.action.PACKAGE_ADDED" />
            <data android:scheme="package"/>
        </intent-filter>
    </receiver>
