我有一个正在开发的应用程序，到目前为止只编辑了 xml，当我尝试调试时我得到了这个：

找不到来源

调试：

Thread [<1> main] (Suspended (exception RuntimeException))

    android:src="@drawable/albumart" />

</RelativeLayout>

如果需要，清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.timmo.tampmusicplayer"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="17" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.timmo.tampmusicplayer.NowPlaying"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

我不断收到此错误。我试过重新安装 sdk 和 adt/eclipse，什么都没有。我根本不明白是什么导致了这个问题。这是使用 android 工具创建的，我什至看不到我的第一个设计...

“找不到源”不是错误。它是 eclipse 的一部分，与您的代码无关。看起来您单击了调试的第一行并被带到了这里。所有“Source not found”都表明 Eclipse 找不到 ActivityThread.java 的源。如果您的应用程序没有启动，那么真正的错误将出现在 Logcat 中。
