Question

我面临着奇怪的问题。当我通过USB在手机上安装应用程序时，它可以工作。但是，当我转移apk并在手机上手动安装时，它会抛出错误。

java.lang.RuntimeException: Unable to instantiate application com.xx.merchant.application.MerchantApplication: java.lang.ClassNotFoundException: Didn't find class "com.xx.merchant.application.MerchantApplication" on path: DexPathList[[zip file "/data/app/com.xx.merchant-U_VFCFO7rdRHN5OC21N8pg==/base.apk", zip file "/data/app/com.xx.merchant-U_VFCFO7rdRHN5OC21N8pg==/split_lib_slice_1_apk.apk", zip file "/data/app/com.xx.merchant-U_VFCFO7rdRHN5OC21N8pg==/split_lib_slice_2_apk.apk", zip file "/data/app/com.xx.merchant-U_VFCFO7rdRHN5OC21N8pg==/split_lib_slice_3_apk.apk", zip file "/data/app/com.xx.merchant-U_VFCFO7rdRHN5OC21N8pg==/split_lib_slice_7_apk.apk"],nativeLibraryDirectories=[/data/app/com.xx.merchant-U_VFCFO7rdRHN5OC21N8pg==/lib/x86, /data/app/com.xx.merchant-U_VFCFO7rdRHN5OC21N8pg==/base.apk!/lib/x86, /data/app/com.xx.merchant-U_VFCFO7rdRHN5OC21N8pg==/split_lib_slice_1_apk.apk!/lib/x86, /data/app/com.xx.merchant-U_VFCFO7rdRHN5OC21N8pg==/split_lib_slice_2_apk.apk!/lib/x86, /data/app/com.xx.merchant-U_VFCFO7rdRHN5OC21N8pg==/split_lib_slice_3_apk.apk!/lib/x86, /data/app/com.xx.merchant-U_VFCFO7rdRHN5OC21N8pg==/split_lib_slice_7_apk.apk!/lib/x86, /system/lib, /system/vendor/lib]]

Answer 1

向gradle文件添加依赖项

compile 'com.android.support:multidex:1.0.1'

还在MultiDex.install班级

上添加Application

public class YouApplication extends Application {

    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }

}
