在我的主要 Activity 上出现“继续加载”对话框后，无法进入第二个 Activity ，并且可以加载几个小时而不会出现错误我使用 facebook acount 套件，我没有看到错误，这里是主要 Activity 源代码 主要 Activity java:
公共(public)类 MainActivity 扩展 AppCompatActivity {
private static final int REQUEST_CODE = 1000;
Button btnContinue;
RelativeLayout rootLayout;

for (Signature signature:info.signatures)

MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
Log.d("KEYHASH", Base64.encodeToString(md.digest(),Base64.DEFAULT));
}
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
}
}
如果需要更多!或者是否还缺少一些东西，我在 Android 编程方面还是个新手，所以......
最佳答案
尝试使用 onCancel 和 onError 方法中的关闭对话框并打印错误来判断。
