我目前正在使用 AIDE 做缺乏计算机，并且我在使用几个类时遇到了问题，我很确定这与 androidx 库和 AIDE 有关，我看到其他人也有类似的问题在这里，无法访问 'androidx.activity.result.ActivityResultCaller'，仅对我来说，我得到 ActivityResult、ActivityResultCallback、ActivityResultContract、ActivityResultLauncher、ActivityCompat 和来自所述类的一些方法以及 ActivityResultCaller 接口的“未知实体”，以及那个人的问题的解决方案对我不起作用，任何建议，这是我的 build.gradle 和 MainActivity，我有一些东西被注释掉了，我一直在搞乱依赖关系

apply plugin: 'com.android.application'

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.2"

    defaultConfig {
        applicationId "com.mycompany.MyApp"
        minSdkVersion 30
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation ('android.arch.core:runtime:+') {
       force = true
}
    implementation 'androidx.activity:activity:1.4.0'
   //implementation 'com.android.support:support-v4:23.+'
    //implementation 'com.android.support:appcompat-v7:22.1.0'
    implementation 'com.android.support:appcompat-v7:27.+'
    //implementation 'androidx.appcompat:appcompat:1.2.0'
     implementation fileTree(dir: 'libs', include: ['*.jar'])
     implementation "androidx.core:core-ktx:1.3.1"
     implementation 'androidx.appcompat:appcompat:1.3.0-alpha01'
}

这是 MainActivity

        }
    }
    
    @Override

    {
        super.startActivityForResult(intent, requestCode);
    }
    /
    private ActivityResultLauncher<Intent> requestPermissionLauncher =
    registerForActivityResult( new ActivityResultContracts.StartActivityForResult(), new ActivityResultCallback<ActivityResult>(){
        @Override

            intent.setData(Uri.parse(String.format("package:%s", new Object[]{PACKAGE_NAME})));
                requestPermissionLauncher.launch(intent);

            }catch(Exception e){
                Intent intent = new Intent();

                activityResultLauncher.launch(intent);
            }
        }
        else{
            ActivityCompat.requestPermissions(this, permissions, 30);
        }
    }
    
}
