关于webview的错误日志

Posted 2022-05-17 黄毛火烧雪下

错误日志1：
Using WebView from more than one process at once with the same data directory is not supported
项目中开启了两个进程：
com.xxx.app.test 和 com.xxx.app.test.pushcore
错误原因：
android P行为变更，不可多进程使用同一个目录webView，需要为不同进程webView设置不同目录
解决办法：
Android 9 prohibit sharing WebView data directory among multiple processes
add below code in your mainApplication file

public void onCreate() 
        ...
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) 
            String processName = getProcessName(this);
            String packageName = this.getPackageName();
            if (!packageName.equals(processName)) 
                WebView.setDataDirectorySuffix(processName);
            
        


private String getProcessName(Context context) 
        if (context == null) return null;
        ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        for (ActivityManager.RunningAppProcessInfo processInfo : manager.getRunningAppProcesses()) 
            if (processInfo.pid == android.os.Process.myPid()) 
                return processInfo.processName;
            
        
        return null;

错误日志2：Failed to load WebView provider: No WebView installed

public class MyWebView extends WebView 

    @Override
    public void setOverScrollMode(int mode) 
        try 
            super.setOverScrollMode(mode);
