我試圖讓所有安裝的應用程序使用intents
和broadcast receiver
,但問題是我從來沒有指向我的onReceive
方法,所以沒有得到任何包名稱。我使用下面的代碼:爲什麼我沒有收到安裝的應用程序廣播?
KillAppBCR.java
public class KillAppBCR extends Activity {
private static final String TAG = "BroadcastReceiver";
BroadcastReceiver receiver;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
IntentFilter filter = new IntentFilter(Intent.ACTION_PACKAGE_ADDED);
receiver = new TestBroadcastReceiver();
registerReceiver(receiver, filter);
Log.e(TAG, "onCreate");
Toast.makeText(KillAppBCR.this,"onCreate",Toast.LENGTH_SHORT).show();
}
TestBroadcastReceiver.java
public class TestBroadcastReceiver extends BroadcastReceiver
{
private static final String TAG = "TestBroadcastReceiver";
@Override
public void onReceive(Context context, Intent intent)
{
String actionStr = intent.getAction();
Log.e(TAG, "onReceive");
Toast.makeText(context,"onReceive",Toast.LENGTH_SHORT).show();
if (Intent.ACTION_PACKAGE_ADDED.equals(actionStr)) {
Uri data = intent.getData();
}
}
}
AndroidManifest.xml中
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.KillAppBCR"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".KillAppBCR"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".TestBroadcastReceiver">
<intent-filter>
<action android:name="com.KillAppBCR" />
</intent-filter>
</receiver>
</application>
</manifest>

問題出在哪裏?請幫助我,我想收到所有安裝的應用程序的廣播。
感謝
那麼,如果你在清單中註冊接收器會發生什麼,如果沒有你的程序運行,它不應該觸發。然後,您只需將已安裝的應用程序添加到可在您使用應用程序時閱讀的列表中。 – 2011-07-19 17:08:42
