应用程序未安装 android 错误

Question

我最近安装了 android SDK 5.1 之后，我收到了以前从未见过的新错误，例如未安装应用程序错误。如果用户单击设备中的应用程序图标，则会出现此错误。您能建议如何解决此问题吗？这是我的清单代码

我已经通过 stackoverflow 检查了这个问题并尝试了解决方案，但没有运气这里是参考链接我已经尝试过link1 link2

Answer 1

根据此处给出的安全说明，检查android:exported是否设置为false。如果是，那么您需要将其设置为true以使用 USB 调试测试手机上的应用程序，如下所示：

<activity 
    android:name=".MainActivity"
    android:exported="true">
  <intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
</activity>

Answer 2

你注册了SplashActivity两次。

<activity android:name="com.srikanth.SplashActivity" >
    </activity>

 <activity
        android:name="com.srikanth.SplashActivity"
        android:label="@string/app_name"
          android:exported="true"
        android:screenOrientation="portrait" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

所以只需要删除其中之一并添加 android:exported="true"
