注意：如果您的项目配置为使用 minSdkVersion 20 或更低版本的 multidex，并且您部署到目标设备 运行 Android 4.4（API 级别 20 ) 或更低，Android Studio 禁用 Instant 运行.
当 运行 在 Android 5.0（API 级别 21） 之前的版本上时，使用 multidex 不足以解决linearalloc 限制 (issue 78035). This limit was increased in Android 4.0 (API level 14), but that did not solve it completely. And on versions lower than Android 4.0, you might reach the linearalloc limit before reaching the DEX index limit. So if you are targeting API levels lower than 14, test thoroughly on those versions of the platform, because your app might have issues at startup or when particular groups of classes are loaded. Code shrinking 可以减少或可能消除这些问题。
你的方法太多了。 dex只能有65536个方法
因此，启用 multidex 如下：
android {
defaultConfig {
// Enabling multidex support.
multiDexEnabled true
}
}
dependencies {
compile 'com.android.support:multidex:1.0.0'
}
像这样创建一个class
public class Multi_Dex extends Application {
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}
现在在您的清单文件中添加这个
<application
android:name=".Multi_Dex"
android:allowBackup="true"
android:icon="@drawable/logo"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
解决这个问题，就像在这个link上描述的那样：developer.android.com/studio/build/multidex
或者试试这个我朋友的 kitkat 或更低版本
android {
defaultConfig {
...
multiDexEnabled true
}
productFlavors {
dev {
// Enable pre-dexing to produce an APK that can be tested on
// Android 5.0+ without the time-consuming DEX build processes.
minSdkVersion 21
}
prod {
// The actual minSdkVersion for the production version.
minSdkVersion 14
}
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'),
'proguard-rules.pro'
}
}
}
dependencies {
compile 'com.android.support:multidex:1.0.1'
}
将此添加到 build.gradle，当您不需要 multidex 功能时，multidex 不是必需的
dexOptions {
preDexLibraries = false
}
