我已经看到许多与此类似的问题,并尝试了几乎所有解决方案。但是没有任何效果。在android模拟器上,app运行良好,但是当我尝试在设备上运行时,它将抛出java.lang.ClassNotFoundException:in.thoughtsmith.jobsmith.SplachScreenActivity。

我看过我的清单,一切看起来都很好

<application
    android:name="in.thoughtsmith.jobsmith.JobSmithApplication"
    android:allowBackup="true"
    android:icon="@drawable/logo_only"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

    <activity

        android:noHistory="true"
        android:theme="@android:style/Theme.Light.NoTitleBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity

        android:label="@string/title_activity_maps" />
    <activity android:name="in.thoughtsmith.jobsmith.JobSearchResultActivity" />
    <activity
        android:name="in.thoughtsmith.jobsmith.LoginActivity"
        />

    <service
        android:name="in.thoughtsmith.jobsmith.LocationCheckerService"
        android:enabled="true"
        android:exported="true" />

    <activity android:name="in.thoughtsmith.jobsmith.FusedApiTestActivity" />
    <activity android:name="in.thoughtsmith.jobsmith.ProfileUpdateActivity"></activity>
</application>


我想明确指出,此应用在模拟器和移动设备中均能正常运行。但是会导致我在其中进行测试的设备上出现问题[但是几天前在同一设备上工作了]。我的设备可能会带点东西吗?

最佳答案

许多设备无法在调试模式下即时运行,因此请执行以下步骤

禁用即时运行-


在文件菜单中单击设置,然后搜索即时运行并取消选中所有复选框,然后再次构建apk。


java - 在我的android应用中找不到类异常-LMLPHP

还要在调试模式下禁用proguard。

debug {
            minifyEnabled false
            useProguard false

        }
