警告: [deprecation] WebViewClientのshouldOverrideUrlLoading(WebView,String)は非推奨になりました

shouldOverrideUrlLoadingはリンクでブラウザを開く関数(falseを返すと新規でブラウザを開かない)

private class CustomWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        return false;
    }
}

↓ Build.VERSION_CODES.N以降専用のアノテーションを追加する

import android.annotation.TargetApi;
import android.os.Build;
import android.webkit.WebResourceRequest;
private class CustomWebViewClient extends WebViewClient {
    @TargetApi(Build.VERSION_CODES.N)
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
        // view.loadUrl(request.getUrl().toString());
        return false;
    }
    @SuppressWarnings("deprecation")
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        return false;
    }
}

警告: [deprecation] WebViewClientのonReceivedError(WebView,int,String,String)は非推奨になりました

エラーハンドラーを以下のように変更

@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
    Log.d(TAG, "failingUrl=" + failingUrl);
}

↓

import android.webkit.WebResourceRequest;
import android.webkit.WebResourceError;
@TargetApi(Build.VERSION_CODES.M)
@Override
public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        Log.d(TAG, error.getErrorCode() + " : " + error.getDescription());
    }
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        Log.d(TAG, "failingUrl=" + request.getUrl().toString());
    }
}
@SuppressWarnings("deprecation")
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
    Log.d(TAG, "failingUrl=" + failingUrl);
}

    }

        return false;
    }
