地理编码器 grpc 失败

Question

Last month of so geocoder has started to fail every time with "grpc failed" error and I can't seem to be able to solve it. I've looked at java.io.IOException: grpc failed but it didn't really solve the problem.

For exampel the code

Geocoder geocoder = new Geocoder(context, Locale.getDefault());
addresses = geocoder.getFromLocation(lat, lng, 1); // Here if fails with "grpc failed"

I've had the same code for years, but it's just lately it has stopped working when I recompile the app and test on an emulator or real device.

If I compile against SDK 25, using build tool 25 it works on an emulator with SDK 25. But if I try on an emulator with SDK 24, 26 or any other SDK version, it will fail with "grpc failed". I've tried to create a new virtual device etc. but same problem.

I have no clue how to fix it and what the problem is.

Current setup: targetSDK/compileSDK 25, build tool 25.0.3, Android Studio 2.3.3, regular emulator. (I've tried other build tools and SDK versions, but problem still remains)

Any ideas?

Answer 1

问题可能是您尝试在主线程中使用 Geocoder，如果您使用 IntentService，您可以在另一个进程中创建此URL选项，尽管您始终可以使用 Asynctask 或类似任务。

Answer 2

Well, this might be too late and for someone else looking for answers, in my case it was internet problem. My internet connection was bad

It's related to Google Play Service on virtual devices. Use API25 and version 7.1.1 for solution.

Here are examples;

When I try on Genymotion and Google Play Services is disabled on virtual device (Error: Service not Available):

Answer 4

I was able to fix a similar problem by adding

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>

to my manifest file

Answer 5

I have solution for exception "java.io.ioexception grpc failed"

Code:

try {
    Geocoder geocoder = new Geocoder(MainActivity.this, Locale.getDefault());
    List addresses = geocoder.getFromLocation(latitude, longitude, 1);
    List addresslist = addresses;
    String address = addresslist.get(0).getAddressLine(0);
    Log.d("add", address);
} catch (IOException e) {
    e.printStackTrace();
}
