Question

我在 gradle 文件中使用了 MultiDexEnable=true 命令来集成 cometChat sdk。但是运行还不错的 Picasso 库现在崩溃了，并出现以下错误。能否请您指导解决方案？

Answer 1

使您的申请class像下面这样

public class MyAppClass extends MultiDexApplication{
@Override
    protected void attachBaseContext(Context newBase) {
        MultiDex.install(newBase);
        super.attachBaseContext(newBase);
    }
}

将此库添加到您的依赖项中

dependencies {
     compile 'com.android.support:multidex:1.0.1'
    //    your dependencies which you are using.

}

Answer 2

启用 build.gradle

选项后，您需要处理多个 dex 文件

& 如果在您的项目中使用应用程序 class 而不是使用 MultiDexApplication 扩展它并在 attachBaseContext

中处理多个 dex 文件

安装MultiDex.installi refer android developer link

例如

public class MyAppClass extends MultiDexApplication{
@Override
    protected void attachBaseContext(Context newBase) {
        MultiDex.install(newBase);
        super.attachBaseContext(newBase);
    }
}

在您的 AndroidManfiest 文件应用程序名称中声明 MyAppClass。

<application
        android:name="MyAppClass"
android:icon="@drawable/ic_launcher"
        android:label="@string/app_name">
//... your other manifest declaration
</application>

已更新gradle

        javaMaxHeapSize "4g"
    }

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

建议

只使用需要的播放服务库，不要添加整个播放服务组。 Refer this link。它也会减少方法计数和未使用的库的数量。

示例

compile 'com.google.android.gms:play-services:8.4.0'

使用这些行（根据所需的功能添加 artifactId（组），如 play-services-fitness play-services-wearable 等）：

compile 'com.google.android.gms:play-services-fitness:8.4.0'
compile 'com.google.android.gms:play-services-wearable:8.4.0'
