6.根目录的build.gradle文件中的依赖路径全部改为https的
7.注销build.gradle文件中的自定义路径(gradle tool插件7.x版本好像不支持自定义路径)
variant.outputs.all {
// 自定义输出路径
if (variant.buildType.name == "release") {
variant.getPackageApplication().outputDirectory = new File(project.rootDir.absolutePath + File.separator + "app/build/outputs/apk/release")
} else {
variant.getPackageApplication().outputDirectory = new File(project.rootDir.absolutePath + File.separator + "app/build/outputs/apk/debug")
}
}
8.适配webView
mWebSettings.setAppCachePath(appCachePath);webView.getSettings().setAppCacheEnabled(false); -> webView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
mWebSettings.setAppCacheEnabled(true) -> mWebSettings.setCacheMode(WebSettings.LOAD_DEFAULT);
9.适配截屏服务：
在manifest.xml文件中添加权限和service
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.MEDIA_PROJECTION" /><service
android:name=".xxxService"
android:foregroundServiceType="mediaProjection"
tools:node="replace"
android:exported="false"/>
10.其他改动待补充
