我签名的APK大小为61 mb，我知道这就是为什么我尝试从Play商店安装应用时收到此错误的原因，但是我不知道如何减小此APK的大小。我也从代码中删除了不需要的代码，但是仍然可以得到这个大小的APK。
这是清单文件代码：
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="8" />
<uses-feature
android:name="android.hardware.bluetooth"
android:required="true" />
<uses-feature
android:glEsVersion="0x00020000"
android:required="true" />
<uses-feature
android:name="android.hardware.camera2"
android:required="true" />
这是我的gradle版本：
ext {
minSdkVersion = 17
targetSdkVersion = 28
compileSdkVersion = 28
buildToolsVersion = '28.0.0'
releaseVersionCode = 1
releaseVersionName = '1.0.3'

请让我知道如何处理此源代码，以便减小apk的大小。
答案 0 :(得分：0)
您可以这样做来减小应用大小（这是一些常见做法）：
除此之外，您还可以尝试
库可能包含未使用的资源。
Gradle可以代表您自动删除资源
在应用的build.gradle文件中启用shrinkResources。
android {
buildTypes {
release {
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android.txt'),
'proguard-rules.pro'
}
}
}
我想说的最终最好的方法是Android App Bundle：
Android应用程序捆绑包是一种新的上传格式，其中包含您应用程序的所有已编译代码和资源，但会延迟APK的生成并登录到Google Play。 在开发人员控制台中查看相关内容并进行更改，这肯定会对您有所帮助。
