java.lang.NoClassDefFoundError: android.support.v7.appcompat.R$layout
引用multiDexEnabled = true android 4.x 及以下的手機不能運行,出現上述錯誤
這個問題我搜索了好久,在國內的搜索上找不到類似問題,所以自己提了一個。其實我已經解決了。
I faced the same issue and fixed it. It is issue with Dex Limit. Because the dex limit is reached, it creates two dex files. Lollipop knows how to read, preLollipop has no idea unless you tell it in application class.
就是dex限制問題,android5.x及以上的都知道,之前的版本要加一句話在 dependencies{}中
android {
compileSdkVersion 21
buildToolsVersion "21.1.0"
defaultConfig {
...
minSdkVersion 14
targetSdkVersion 21
...
// Enabling multidex support.
multiDexEnabled true
}
...
}
dependencies {
compile 'com.android.support:multidex:1.0.0'
}
還要在Manifest.xml的application 標簽中加入以下一句話:
<?xml version="1.0" encoding="utf-8"?>
package="com.example.android.multidex.myapplication">
...
android:name="android.support.multidex.MultiDexApplication">
...
解決
