Question

我想在我的应用程序启动时自动打开gps，就像其他应用程序一样。我有以下代码：

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        LocationRequest mLocationRequest = new LocationRequest();
        mLocationRequest.setInterval(1000);
        mLocationRequest.setFastestInterval(1000);
        mLocationRequest.setPriority(
                 LocationRequest.PRIORITY_HIGH_ACCURACY);
    }

许可：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    package checker.coin.crypto.wingcrony.by.cryptocoinchecker;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;

import com.google.android.gms.common.api.GoogleApiClient;

public class MainActivity extends Activity {

    private GoogleApiClient client;
    private WebView view;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        view = (WebView) this.findViewById(R.id.webView);
        view.getSettings().setJavaScriptEnabled(true);
        view.getSettings().setDomStorageEnabled(true);
        view.setWebViewClient(new MyBrowser());
        view.loadUrl("file:///android_asset/www/index.html"); //try js alert
        view.setWebChromeClient(new WebChromeClient()); // adding js alert support


    }

    private class MyBrowser extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if (url.startsWith("tel:") || url.startsWith("sms:") || url.startsWith("smsto:") || url.startsWith("mailto:") || url.startsWith("mms:") || url.startsWith("mmsto:") || url.startsWith("market:") || url.equals("http://wingcrony.com/?actie=donate")) {
                Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
                startActivity(intent);
                return true;
            }
            else {
                view.loadUrl(url);
                return true;
            }
        }
    }

    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if ((keyCode == KeyEvent.KEYCODE_BACK) && view.canGoBack()) {
            view.goBack(); //method goback()
            return true;
        }

        return super.onKeyDown(keyCode, event);
    }
}
