Android签名/未签名的两个.apk文件均处于停止状态

如何解决Android签名/未签名的两个.apk文件均处于停止状态

我使用网络视图在android应用程序中转换了网站，但该网站一直停留在我的客户端移动设备上。他的手机是morto E4，API级别是25，我将应用程序的最小SDK设置为21，最大设置为29。我不明白这个问题。我的手机运行良好，我还测试了3部手机。以下是我的代码以及我在代码中使用的所有内容。请帮我，如果需要的话，我不会上传我应用的徽标。

Gradle-app

    enter code here
apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsversion "29.0.3"

    defaultConfig {
        applicationId "com.farah.tawaqqo"
        minSdkVersion 21
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation filetree(dir: "libs",include: ["*.jar"])
    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'

}
