错误：从minSdkVersion 16升级到minSdkVersion 23的软件包android.support.multidex不存在

Question

My app is not supporting Android 4.x and 5.x anymore, only Android 6.0 and higher. For that reason, in my app/build.gradle I changed minSdkVersion 16 to minSdkVersion 23 . After doing that, I have started to get this error when I try to run the app:

error: package android.support.multidex does not exist
error: cannot find symbol variable MultiDex

In one of my .java files, I see the errors in the following lines:

import android.support.multidex.MultiDex;
MultiDex.install(this);

Should I simply not use MultiDex because Android 6.0 and higher do not need that anymore? This is considering that my app will not support Android 5.x and lower anymore. Thank you.

Answer 1

The solution to this problem is to add the following in Dependencies in build.gradle :

dependencies {
  implementation 'com.android.support:multidex:1.0.3'
}

Answer 2

尝试在build.gradle（app）中将multiDexEnabled设置为true

Answer 3

If your minSdkVersion is set to 21 or higher, all you need to do is set multiDexEnabled to true in your module-level build.gradle file, as shown here:

android {
    defaultConfig {
        ...
        minSdkVersion 21 
        targetSdkVersion 28
        multiDexEnabled true
    }
    ...
}

Answer 4

I needed to change

import android.support.multidex.MultiDex

to

import androidx.multidex.MultiDex

to reference the "newer" MultiDex 's location (version 1.0.3 in my case).
