每当我尝试通过启动谷歌登录意图登录时,它直接转到onActivityResult,而我没有机会选择一个帐户.
所有它确实是屏幕上的dimm,但选择帐户的窗口没有显示.
然后登录失败,出现此ApiException:
java.lang.classNotFoundException: com.google.android.gms.common.api.Scope
和
java.lang.RuntimeException: Canvas: trying to draw too large(256000000bytes) bitmap.

我所有使用的依赖项都是最新的,我的凭据(oAuth client-id)都设置正确,我尝试了其他类似问题的解决方案,但没有一个解决了我的问题,我还检查了用户是否已注销完全来自设备,问题不断重现.
这是我的登录活动:
public class Login extends Activity implements Googleapiclient.OnConnectionFailedListener, Googleapiclient.ConnectionCallbacks {
private static final String TAG = "LoginProcess";
SignInButton gsignInButton;
private static final int RC_SIGN_IN = 1;
DatabaseReference mRef;
FirebaseAuth mAuth;
FirebaseAuth.AuthStateListener mAuthListener;
GoogleSignInoptions gso;
Googleapiclient mGoogleapiclient;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.welcomescreenlogin);
mAuth = FirebaseAuth.getInstance();
gso = new GoogleSignInoptions.Builder(GoogleSignInoptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.default_web_client_id))
.requestemail()
.build();
mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
gsignInButton = findViewById(R.id.sib);
gsignInButton.setColorScheme(SignInButton.COLOR_DARK); // wide button style
gsignInButton.setonClickListener(myhandler);
}
View.OnClickListener myhandler = new View.OnClickListener() {
public void onClick(View v) {
signIn();
}
};
public void signIn() {
Intent signInIntent = mGoogleSignInClient.getSignInIntent();
startActivityForResult(signInIntent, RC_SIGN_IN);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RC_SIGN_IN) {
Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
try {
// Google Sign In was successful, authenticate with Firebase
GoogleSignInAccount account = task.getResult(ApiException.class);
firebaseAuthWithGoogle(account);
} catch (ApiException e) {
// Google Sign In Failed, update UI appropriately
Log.w(TAG, "Google sign in Failed", e); //this is where it always lands.
Toast.makeText(this, "login Failed", Toast.LENGTH_SHORT).show();
// ...
}
}
}

我不知道问题的原因是什么,如何解决这个问题并弹出帐户选择窗口?

而不是上面的ApiExeption我得到这个错误:

我相信我设置oAuth的方式出了问题(由Firebase生成的自动)
解决方法:
选项1 – 确保在Firebase控制台的Firebase身份验证方法中启用了Google登录.默认情况下,未启用Google登录.
选项2 – 在AndroidManifest.xml文件中,在标记下添加以下行以支持高内存支持,以防Google登录弹出窗口需要更多内存.甚至可以在应用程序标记中使用此命令加载大图像 – largeHeap为true~在这种情况下为您的启动器图像.
<application
android:hardwareAccelerated="true"
android:largeHeap="true" >
选项3 – 尝试使用此代码来使用Firebase实施Google登录,它应该可以正常运行.
public class LoginActivity extends AppCompatActivity {
private GoogleSignInClient mGoogleSignInClient;
private FirebaseAuth mAuth;
private int permissions = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
SignInButton authButton = findViewById(R.id.home_auth_button);
GoogleSignInoptions gso = new GoogleSignInoptions.Builder(GoogleSignInoptions.DEFAULT_SIGN_IN)
.requestIdToken("xxxxxxxxxxxx.apps.googleusercontent.com").requestemail().build();
mAuth = FirebaseAuth.getInstance();
mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
authButton.setonClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
signIn();
}
});
}
private void signIn() {
Intent signInIntent = mGoogleSignInClient.getSignInIntent();
startActivityForResult(signInIntent, 0);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0) {
Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
try {
GoogleSignInAccount account = task.getResult(ApiException.class);
if (account != null) {
firebaseAuthWithGoogle(account);
} else{
Log.w("AUTH", "Account is NULL");
Toast.makeText(LoginActivity.this, "Sign-in Failed, try again later.", Toast.LENGTH_LONG).show();
}
} catch (ApiException e) {
Log.w("AUTH", "Google sign in Failed", e);
Toast.makeText(LoginActivity.this, "Sign-in Failed, try again later.", Toast.LENGTH_LONG).show();
}
}
}
private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
Log.d("AUTH", "firebaseAuthWithGoogle:" + acct.getId());
AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
mAuth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Log.d("AUTH", "signInWithCredential:success");
startActivity(new Intent(LoginActivity.this, AnotherActivity.class));
Toast.makeText(LoginActivity.this, "Sign-in successful!", Toast.LENGTH_LONG).show();
} else {
Log.w("AUTH", "signInWithCredential:failure", task.getException());
Toast.makeText(LoginActivity.this, "Sign-in Failed, try again later.", Toast.LENGTH_LONG).show();
}
}
});
}
}
请注意您需要使用构建器传递requestIdToken(“xxxx”)的GoogleSignInoptions.Builder.这是一个您可以在Firebase身份验证标签下找到的网址 – >登录方法 – > Google – > Web SDK配置 – > Web客户端ID.
希望这能回答您的疑问.
