Question

只有Mi pad在运行应用程序时出现该问题。为了解决我遇到的问题 1.卸载该应用，然后重试连接，但出现相同的错误 2.在我的android studio中禁用即时运行 3.构建gradle中的用户多办公桌

其他项目正在同一标签中的同一Android Studio中工作

任何人都知道如何解决该问题。

应用程序类

public class ApplicationDetails extends MultiDexApplication {


    public static boolean isAppOpen = false;

    private static ApplicationDetails mInstance;
    public static final String TAG = ApplicationDetails.class.getSimpleName();


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


    @Override
    public void onTerminate() {
        // TODO Auto-generated method stub
        super.onTerminate();
        isAppOpen = false;
    }
}

构建gradle

defaultConfig {
        applicationId "com.ucsvirtualschool"
        minSdkVersion 19
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables { useSupportLibrary = true    }
        dataBinding {
            enabled = true
        }
        multiDexEnabled true
        vectorDrawables.useSupportLibrary = true
        ndk {
            abiFilters "armeabi", "x86"
        }
    implementation 'com.android.support:multidex:1.0.3' //for solve issue in mi tab

Answer 1

根据您提供的代码段，我会想到两件事。

您已经使用了MultiDexApplication，因此不需要覆盖attachBaseContext方法
可能会发生，但是ApplicationDetails类没有将其放入第一个dex文件的可能性很小，这就是应用程序崩溃的原因。您可以尝试在第一个dex文件中声明所需的类。 Declare classes required in the primary dex file

Answer 2

也许您可以尝试以下操作：在.application.ApplicationDetails中的“ com.ucsvirtualschool.application.ApplicationDetails”中填写应用程序名称“ AndroidManifest.xml”。

<application
    android:name="com.ucsvirtualschool.application.ApplicationDetails"
    android:allowBackup="false"
    android:hardwareAccelerated="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    tools:replace="android:allowBackup">
