早些时候我使用的是 Eclipse IDE，由于我使用了很多来自 Amazon 的库，我开始收到 65K 方法引用错误。所以我从 Eclipse 转移到了 Android studio 最新的预览频道版本。我的毕业典礼看起来像：
apply plugin: 'com.android.application'
android {
packagingOptions {
exclude 'META-INF/LICENSE'
}
signingConfigs {
xxx {
keyAlias 'xxx'
keyPassword 'xxx'
storeFile file('path')
storePassword 'xxx'
}
}
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.xxx.app"
versionCode 4
versionName "0.4"
// Enabling multidex support.
multiDexEnabled true
}
productFlavors {
// Define separate dev and prod product flavors.
dev {
// dev utilizes minSDKVersion = 21 to allow the Android gradle plugin
// to pre-dex each module and produce an APK that can be tested on
// Android Lollipop without time consuming dex merging processes.
minSdkVersion 21
}
prod {
// The actual minSdkVersion for the application.
minSdkVersion 15
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
signingConfig signingConfigs.xxx
}
debug {
signingConfig signingConfigs.xxx
minifyEnabled false
}
}
dexOptions {
incremental true
javaMaxHeapSize "4g"
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
lintOptions {
abortOnError false

}
}
dependencies {

}
我的 gradle 构建成功，并且我已将构建变体设置为 devDebug，但是当我单击运行（绿色图标）时，该应用程序未安装在设备上。我等了 45 分钟，但它只是显示我的 Gradle 任务正在运行。
我有扩展 MultiDexApplication 的应用程序类，还添加了 attachBaseContext 方法。
@Override
protected void attachBaseContext(Context base) {
MultiDex.install(this);
super.attachBaseContext(base);
}
我现在正在尝试运行该应用程序超过一天，不幸的是没有什么对我有用。我的申请中还有什么遗漏的吗？欢迎所有建议。
