Question

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是在我将它安装到我的设备上后，它给出了 “应用程序MusicShare（进程com.example.musicshare）已意外停止。请再试一次”。

我的设备是Galaxy S2，我从bin文件夹中获取了apk。我尝试过使用“未使用未签名密钥导出而无法安装。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！
