使用以下链接:https://developers.google.com/identity/sign-in/android/start-integrating我已经将谷歌登录集成到我的项目中。代码与下面的链接相同:
public class MainActivity extends AppCompatActivity {
GoogleApiClient mGoogleApiClient;
Button btn;
int RC_SIGN_IN =100;
String TAG ="Google";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build();
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this /* FragmentActivity */, new GoogleApiClient.OnConnectionFailedListener() {
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
}
} /* OnConnectionFailedListener */)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
SignInButton signInButton = (SignInButton) findViewById(R.id.sign_in_button);
signInButton.setSize(SignInButton.SIZE_STANDARD);
signInButton.setScopes(gso.getScopeArray());

btn.setOnClickListener(new View.OnClickListener() {

这可以在Kitkat设备上找到,但在android M设备上它显示
状态{statusCode=DEVELOPER_ERROR,resolution=null}
首先,我认为可能是Json文件问题,但如果是,它不应该在任何设备上工作。它在kitkat 4.2.2设备上运行成功,但在android M设备上失败。那么这个怎么了?
在所有答案之后,我做了以下简单的代码:
GoogleSignInOptions gso=新的GoogleSignInOptions.Builder(GoogleSignInOperations.DEFAULT_SIGN_IN(.requestEmail((.build((;
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this, new GoogleApiClient.OnConnectionFailedListener() {
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
}
})
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, RC_SIGN_IN);
它对我的电子邮件Id有效,但当我在其他设备和不同的电子邮件上使用相同的代码时,它会显示相同的错误。当我尝试添加server_client id时,它显示status=12501错误。我仍然不知道代码出了什么问题。
随着Android的推出,棉花糖被引入了Android运行时权限,所以如果你的设备的系统版本至少是6.0,你应该为用户提供这个功能
阅读此处:https://developer.android.com/training/permissions/requesting.html
要避免实现此功能,请转到您的app/build.gradle
并降级CCD_ 2至22。所以你的build.gradle
应该看起来像:
defaultConfig {
applicationId "com.example.piotr.netgururecruit"
minSdkVersion 12
targetSdkVersion 22 //downgrade this value to 22 or 21 to avoid runtime permissions
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
Since 6.0 some permissions are considered as "dangerous".
为了保护用户,他们必须在运行时获得授权,这样用户才能知道这是否与他的操作有关。您可以在下面的链接上查看完整的示例:https://www.learn2crack.com/2015/10/android-marshmallow-permissions.html
在menifest.xml 中添加这2个权限
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
you have to pass your google_server_client_id
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.google_server_client_id))
.requestServerAuthCodegetString(R.string.google_server_client_id)
.requestEmail()
.build();
mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
.enableAutoManage(getActivity(), this)
.addApi(Plus.API, Plus.PlusOptions.builder().build())
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
