Cannot resolve symbol 'forName'

"Cannot resolve symbol 'forName'"是一个编译器错误，意味着编译器无法识别"forName"方法。这个方法是Java中的一个静态方法，属于Class类，用于根据类名获取对应的Class对象。如果出现这个错误，可能是因为你没有正确导入java.lang.Class类或者没有正确使用Class.forName()方法。你需要确保你的代码中正确导入了java.lang.Class类，并且正确使用了Class.forName()方法。

cannot resolve symbol MapView

这个错误通常出现在使用Google Maps API时。可能是因为您没有正确导入Google Play服务库或没有正确配置API密钥。

您需要在项目中的build.gradle文件中添加以下依赖项：

dependencies {
    implementation 'com.google.android.gms:play-services-maps:17.0.0'
}

此外，确保您已经在AndroidManifest.xml文件中添加了以下权限：

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

最后，请确保您在Google Cloud Console中正确配置了API密钥，并将其添加到您的AndroidManifest.xml文件中：

<meta-data
    android:name="com.google.android.geo.API_KEY"
    android:value="YOUR_API_KEY"/>

请注意，您需要启用Maps SDK for Android API和Places API才能使用Google Maps API。

Cannot resolve symbol MyApplication

The error "Cannot resolve symbol MyApplication" typically occurs when the compiler cannot find the reference to the MyApplication class in your codebase. This class is usually automatically generated when you create a new Android application project.

To resolve this issue, you can try the following steps:

1. Make sure that you have defined the MyApplication class correctly in your code. It should extend the Application class and be declared in the AndroidManifest.xml file using the `android:name` attribute.

2. Clean and rebuild your project. In Android Studio, you can go to "Build" > "Clean Project" and then "Build" > "Rebuild Project" to regenerate any missing files or references.

3. Check if you have any import statements missing for the MyApplication class. Make sure that you have imported the correct package where the MyApplication class is located.

4. If you have recently made any changes to your project's structure or dependencies, double-check if there are any conflicts or errors in your build.gradle files.

5. If the issue persists, try restarting Android Studio or re-importing the project.

If none of these steps resolve the issue, please provide more context or the relevant code snippets so that I can assist you further.
