Answer 1

注意：如果您的项目配置为使用 minSdkVersion 20 或更低版本的 multidex，并且您部署到运行 Android 4.4（API 级别 20）或更低版本的目标设备，Android Studio 将禁用 Instant Run。

在 Android 5.0（API 级别 21） 之前的版本上运行时，使用 multidex 不足以解决线性分配限制 (issue 78035). 此限制在 Android 4.0（API 14级），但这并没有完全解决它。在低于 Android 4.0 的版本上，您可能会在达到 DEX 索引限制之前达到 linearalloc 限制。因此，如果您的目标 API 级别低于 14，请在这些平台版本上进行彻底测试，因为您的应用程序在启动时或加载特定类组时可能会出现问题。 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。

所以，启用multidex如下：

android {    
defaultConfig {
    // Enabling multidex support.
    multiDexEnabled true
}  
}
dependencies {
compile 'com.android.support:multidex:1.0.0'
}

像这样创建一个类

public class Multi_Dex extends Application {
@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
}
}

现在在你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，就像在这个链接上描述的那样：developer.android.com/studio/build/multidex

或者试试我朋友的 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'
}

Answer 2

将此添加到 build.gradle，不需要 multidex 功能，而您不需要 multidex 功能

dexOptions {
    preDexLibraries = false
}
