我有一个分为两个的项目：基本代码模块和特定于应用程序的代码模块。

我正在尝试使用GCMIntentService，但在应用程序开始运行时遇到此错误：

对于错误的描述，找不到类。我已经读过在应用程序所在的包中必须有一个GCMIntentService类。

所以这是我的应用程序的清单：

包中实际上有一个GCMIntentService类，当我在getDefaultIntentServiceClassName类的GCMBroadcastReceiver方法中放置一个断点时，该类的路径字符串似乎是正确的。我仍然得到这个错误。

我已经在Stack Overflow尝试了很多解决方案，但他们似乎都没有解决它。

1 个答案:

答案 0 :(得分：0)

经过大量的时间，我终于找到了解决方案。

这是abc.cpp的一部分：

build.gradle

我的android { compileSdkVersion 18 buildToolsVersion "21.1.2" sourceSets { main { manifest.srcFile 'AndroidManifest.xml' java.srcDirs = ['src\\main\\java','src\\test\\java'] // Line 1 resources.srcDirs = ['src\\main\\java','src\\test\\java'] // Line 2 aidl.srcDirs = ['src\\main\\java','src\\test\\java'] renderscript.srcDirs = ['src\\main\\java','src\\test\\java'] res.srcDirs = ['res'] assets.srcDirs = ['assets'] } instrumentTest.setRoot('tests') } } 包裹在GCMIntentService内。 我删除了文件夹src/main/java并将包放在main/java内。

然后我更改了src和Line 1，如上所示：

Line 2

它开始工作了。
