Fatal Exception: java.lang.RuntimeException:Using WebView from more than one process at once with the same data directory is not supported

Question

1.When I in Fragment onCreateView method inflater.inflate(webview_layout, container, false) on Android 9 may Crash with blow log:

    Fatal Exception: java.lang.RuntimeException:Using WebView from more than one process at once with the same data directory is not supported. https://crbug.com/558377

2.I try add blow code in Application onCreate method

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
    String processName = getProcessName();
    if (!MAIN_PROCESS.equals(processName)) {
        WebView.setDataDirectorySuffix(getProcessName() + ".webview");
    }
}

but some Android mobile phone alse Crash with same reason,and I don't use webview with multi process, then I try add this code in Fragment onCreateView before inflater.inflate(webview_layout, container, false)

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
    String processName = getProcessName();
    try {
        WebView.setDataDirectorySuffix(processName);
    } catch (Throwable e) {
        // ignore
    }
}

But I also get some the same crash report in PCAM10\PCEM00\PCAT10... and I can't reappear this crash local.

Is also some other reason with this Crash?

Answer 1

using this code in Application class before initializing Admob solve my problem:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
        val process = getProcessName()
        if (packageName != process) WebView.setDataDirectorySuffix(process)
    }

MobileAds.initialize(this)
