我正在制作一个简单的音乐播放器应用程序。它已经在我的模拟器上完美运行，但在我的设备上安装它后，它给出
“应用程序MusicShare（进程 com.example.musicshare）已意外停止。请重试”。
我的设备是 Galaxy S2，我从 bin 文件夹中获取了 apk。我尝试使用“导出 w/o 未签名密钥，但无法安装它。这是清单：
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.musicshare"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name=".AndroidBuildingMusicPlayerActivity"
android:label="@string/app_name"
android:configChanges="keyboardHidden|orientation">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".PlayListActivity" />
</application>
</manifest>
任何帮助将不胜感激。谢谢！
