apk安裝報錯

最近在公司導入一個項目總報一個錯：

Caused by: java.lang.ClassNotFoundException: Didn't find class "com.app.Application"

    java.lang.RuntimeException: Unable to instantiate application com.app.Application: java.lang.ClassNotFoundException: 
	Didn't find class "com.app.Application" on path: DexPathList[[zip file "/data/app/com.app-2/base.apk", zip file "/data/app/com.app-2/split_lib_dependencies_apk.apk", zip file "/data/app/com.app-2/split_lib_slice_0_apk.apk", zip file "/data/app/com.app-2/split_lib_slice_1_apk.apk", zip file "/data/app/com.app-2/split_lib_slice_2_apk.apk", zip file "/data/app/com.app-2/split_lib_slice_3_apk.apk", zip file "/data/app/com.app-2/split_lib_slice_4_apk.apk", zip file "/data/app/com.app-2/split_lib_slice_5_apk.apk"

然而項目中存在這個類。經過多次的測試，最終在百度上找到了一份解決方案：

dependencies { 
classpath ‘com.android.tools.build:gradle:2.3.1’ 
}

把這個換成小版本:

dependencies { 
classpath ‘com.android.tools.build:gradle:2.2.3’ 
}

將Android Plugin Version 換成2.2.3，問題解決。
