android - 找不到符号变量 FLAG_ACTIVITY_CLEAR_TASK

Question

将支持版本更新到 27.0.0 编译器后出现错误

找不到符号变量 FLAG_ACTIVITY_CLEAR_TASK。

Is this variable removed? What use instead?

代码示例:

 Intent intent = new Intent(SetNewPasswordActivity.this, SignInActivity.class);
 intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | IntentCompat.FLAG_ACTIVITY_CLEAR_TASK);

Answer 1

cannot find symbol variable FLAG_ACTIVITY_CLEAR_TASK

你应该使用 Intent.FLAG_ACTIVITY_CLEAR_TASK .

If set in an Intent passed to Context.startActivity(), this flag will cause any existing task that would be associated with the activity to be cleared before the activity is started.

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
