常见 deprecation

1. cookieManager.removeAllCookie
   CookieManager | Android Developers

This method was deprecated in API level 21. Use [removeAllCookies(android.webkit.ValueCallback)](https://developer.android.com/reference/android/webkit/CookieManager#removeAllCookies(android.webkit.ValueCallback%3Cjava.lang.Boolean%3E)) instead.

2. VERSION.SDK
   Build.VERSION | Android Developers

This field was deprecated in API level 15. Use [SDK_INT](https://developer.android.com/reference/android/os/Build.VERSION#SDK_INT) to easily get this as an integer.

3. versionCode
   PackageInfo | Android Developers

This field was deprecated in API level 28. Use [getLongVersionCode()](https://developer.android.com/reference/android/content/pm/PackageInfo#getLongVersionCode()) instead, which includes both this and the additional [versionCodeMajor](https://developer.android.com/reference/android/R.styleable#AndroidManifest_versionCodeMajor) attribute. The version number of this package, as specified by the tag's [versionCode](https://developer.android.com/reference/android/R.styleable#AndroidManifest_versionCode) attribute.

解决方案：

PackageInfo pInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), PackageManager.GET_CONFIGURATIONS);
versionCode =  pInfo.versionCode;

改为：

PackageInfo pInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), PackageManager.GET_CONFIGURATIONS);
versionCode =  pInfo.getLongVersionCode();
