Android Google登录例外

问题描述 投票:3回答:1

我想获得当用户无法使用Google登录登录我的应用时导致的异常。例如,在handleSignInResult(@NonNull Task<GoogleSignInAccount> completedTask)方法中,我使用此方法:

private void handleSignInResult(@NonNull Task<GoogleSignInAccount> completedTask) {
    try {
        account = completedTask.getResult(ApiException.class);
        if(isSignedIn()) {
            Toast.makeText(this, "Success!", Toast.LENGTH_SHORT).show();
            startActivity(new Intent(MainActivity.this, Home.class));
        }
    } catch (ApiException e) {
            Toast.make(this, "Failed to login because: " + e.getCause(), Toast.LENGTH_LONG).show();
        }
    }
}

这有助于我找出错误的原因。但最常见的原因是,当没有选择帐户时,此代码返回null。 但是当我没有选择帐户时,我想制作一个Toast

Toast.makeText(this, "Failed to login because: No account selected!", Toast.LENGTH_LONG).show();

我认为这可以通过开关盒实现,但我不知道该怎么做。

这是我应该使用的:

private void handleSignInResult(@NonNull Task<GoogleSignInAccount> completedTask) {
    try {
        account = completedTask.getResult(ApiException.class);
        if(isSignedIn()) {
            Toasty.success(this, "Success!", Toast.LENGTH_SHORT, true).show();
            startActivity(new Intent(MainActivity.this, Home.class));
        }
    } catch (ApiException e) {
        if(e.getCause() != null) {
            Toast.makeText(this, "Failed to login because: " + e.getCause(), Toast.LENGTH_LONG).show();
        }
        else {
            Toast.makeText(this, "Failed to login because: No account Selected!", Toast.LENGTH_LONG).show();
        }
    }
}`
