Android请求权限时GrantPermissionsViewModel报包未找到错误排查

在Android应用中请求蓝牙权限时，底层GrantPermissionsViewModel输出错误日志**"Package com.blackholeofphotography.ble not found"**，权限申请弹窗无法弹出。推测弹窗问题是该错误的连锁反应，需先解决包找不到的问题。

怀疑是XML或Gradle配置缺失，但无法定位具体项，已通过Stack Overflow和DuckDuckGo搜索未获有效线索。

尝试过ActivityCompat.requestPermissions和ActivityResultLauncher两种权限申请方式，结果一致。错误来自GrantPermissionsViewModel.kt第284行，原因是packageInfoLiveData为空或未加载，但包名确认正确，疑惑是否因为是调试版本未通过Play商店分发导致。

已将问题简化为仅含一个按钮的测试应用，相关代码如下：

MainActivity.java #

package com.blackholeofphotography.ble;

import static android.Manifest.permission.BLUETOOTH;

import android.content.pm.PackageManager;
import android.os.Bundle;
import android.util.Log;

import androidx.core.app.ActivityCompat;

import androidx.core.view.ViewCompat;
import androidx.core.view.WindowInsetsCompat;

public class MainActivity extends AppCompatActivity
{
   @Override
   protected void onCreate (Bundle savedInstanceState)
   {
      super.onCreate (savedInstanceState);
      Log.d ("ble", "onCreate");

      EdgeToEdge.enable (this);
      setContentView (R.layout.activity_main);
      ViewCompat.setOnApplyWindowInsetsListener (findViewById (R.id.main), (v, insets) ->
      {
         Insets systemBars = insets.getInsets (WindowInsetsCompat.Type.systemBars ());
         v.setPadding (systemBars.left, systemBars.top, systemBars.right, systemBars.bottom);
         return insets;
      });

      final Button button = findViewById (R.id.button);
      button.setOnClickListener (new View.OnClickListener ()
      {
         @Override
         public void onClick (View v)
         {
            Log.d ("ble", "onClick");
            if (ActivityCompat.checkSelfPermission (getApplicationContext (), BLUETOOTH) != PackageManager.PERMISSION_GRANTED)
            {
               Log.i ("ble", "requestPermissions");
               ActivityCompat.requestPermissions (MainActivity.this, new String[] { BLUETOOTH }, 0);
            }
            else
            {
               Log.i ("ble", "Permission Granted");
            }
         }
      });
   }
}
