（在Nexus 5上Android Lollipop，Android Studio RC2）：
build.gradle以下是 android {
compileSdkVersion 21
buildToolsVersion "21.1.0"
defaultConfig {
applicationId "com.my.package"
minSdkVersion 21
targetSdkVersion 21
versionCode 3
versionName "0.1-alpha"
multiDexEnabled true
}
...
compile 'com.android.support:multidex:1.0.0'
：
BaseApplication我的MultiDexApplication来自public class BaseApplication extends MultiDexApplication {
Manifest这是我的 <application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme"
android:name=".BaseApplication">
{{1}}
答案 0 :(得分：0)
清单文件可能有问题吗？在＆＃34; AndroidManifest.xml＆＃34; name属性值必须设置为＆＃34; .BaseApplication＆＃34;
<application
android:icon="@drawable/icon"
android:label="@string/app_name"
android:name=".BaseApplication">
