Google Play服务和NoClassDefFoundError

时间:2015-05-06 14:36:12

标签: android android-studio google-play-services wear-os

我的应用程序工作正常,直到今天。要与可穿戴模块(我使用Android Studio)进行一些集成,我必须将Google Play服务从6.1.0更新到7.3.0(最新版本)。我也使用外部库,我知道它工作正常,没有任何问题。

当我使用新的Google Play服务版本更新我的gradle文件时,我在运行时得到NoClassDefFoundError(在我的外部库上抱怨)。我已经尝试了一切,但没有任何作用(确保.jar正常,实际导出,清理1000次,重建,删除构建文件夹等)。如果我将Google Play服务设置为6.1.11,该应用程序将按原样运行。

这让我发疯了......

我的build.gradle

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.google.android.gms:play-services:7.3.0'
compile files('libs/mylibrary.jar')

}

Google Wear尚不支持Google Play Services v7.x.

因此,您需要在可穿戴项目中使用Google Play Services v6.x,例如在您的build.gradle穿戴项目文件中:

dependencies {
    compile 'com.google.android.gms:play-services:6.5.87'
}

但是在您的移动(手持)项目中,您可以使用最新的v7.x库版本,如果您真的需要它,例如:

dependencies {
    wearApp project(':yourWearProjectName')
    compile 'com.android.support:appcompat-v7:22.0.0+'
}

.apk的限制为~65000种方法。 Google Play服务随着每个版本的增长而增长,当您将它们包含在项目中时,您很可能跳过该方法计数限制。解决方案是仅使用您需要的模块。
