Android phone 不启动开发的apk

Question

我今天开始使用 Android Studio 并创建了一个简单的 Hello World 应用程序。

我已经将它构建为 APK 文件。然后我将这个 APK 文件移到了我的 phone 上。我已经安装了这个 APK。 phone桌面上的图标出现了，但是我点击它的时候出现错误：Application not found.

Phone: 小米红米 Note 7, 安卓 10.

Android Studio 项目是为 Andriod 系统构建的，从 Android 5 Lollipop 开始。

我已经尝试解决这个问题并尝试了不同的方法。考虑到，我不确定问题出在哪里（小米系统，android os，AndroidManifest 文件，权限等...）我尝试了不同的方法：

万一小米有问题phone:

我试过关闭MIUI优化，开启USB调试，开启U盘安装。那是在 Android 开发人员设置中。这没有帮助，phone 开始出现故障。

以防万一，如果问题出在我构建 APK 的方式上：

我已经尝试构建它构建 > 构建捆绑包/APK(s) > 构建 APK(s)。当我看到我的 phone 说“找不到应用程序”时，我尝试通过 Build > Generate Signed Bundle/APK... 然后我都尝试了调试和发布。没有任何帮助。

当我想到它可能与从不同来源安装应用程序的权限有关时，我尝试禁用 Google Play 保护扫描。这也没有帮助。

我正在深入研究AndroidManifest.xml，也许问题就在那里，但似乎没问题。这是一个和平的代码：

 <application
 android:allowBackup="true"
 android:icon="@mipmap/ic_launcher"
 android:label="@string/app_name"
 android:roundIcon="@mipmap/ic_launcher_round"
 android:supportsRtl="true"
 android:theme="@style/Theme.Music">
 <activity
     android:name=".MainActivity"
     android:exported="false">
     <intent-filter>
         <action android:name="android.intent.action.MAIN"/>
         <category android:name="android.intent.category.LAUNCHER"/>
     </intent-filter>
 </activity>
 </application>

所以我真的不知道，我该怎么办以及如何解决它。有任何想法吗？谢谢

编辑：

我的 PC 速度很慢，所以 Android android 工作室中的模拟器无法正常工作，因此我不能说模拟器会怎样。

此外，我查看了 phone 上的文件夹 Android/data/，但没有找到“com.example.music”包（这应该是我的应用程序的包名称）。但是我不确定，这个包应该在这个文件夹中。

我用 APK 分析器扫描了这个已安装的应用程序，它指出，该应用程序的包是“com.example.music”，并且它存在于 phone 上的某处。这意味着，该应用基本上应该 link 它，并且它应该在某个地方。

所以我尝试通过 logcat 调试这个东西，我收到的是：

Answer 1

你能不能不尝试通过调试直接构建到设备上？您应该检查 logcat，确保构建成功，然后尝试通过 USB 调试安装应用程序。
