下载Google Play服务

Question

In my android app I use google play services to view google maps

When a device does now have google play services installed, android shows a button says "Get Google Play Services" this button is from android itself, i did not create it.

the problem is that when ever user click on that button, app crashes.

I tried to trace the code and debug but there is no code for this ( i did not create any code for it)

I get this error, not sure how this can be resolved.

any ideas?

Thanks

Answer 1

You receive this error because you are running your code on an Android device that doesn't have the Google Play Store.

You can check if your intent will succeed like this:

if (intent.resolveActivity(getPackageManager()) != null) {
    startActivity(intent);
} else {
    //There isn't an app that handle your intent
}
