我正在开展一个项目，如果你在主要活动（MainActivityWithButtons）上按下Break In，它会打开一个页面供你输入你的地址，当你按下按钮时它就会发送一条短信特定的消息。我需要使用布尔值来选择该消息。如果你点击中断，它会将一个名为breakIn的布尔值设置为true。我现在需要访问breakIn布尔值和值（true或false，在本例中为true），以便使用if else语句来选择消息。我的问题是，即使我的布尔设置为真，我按下按钮发送短信，我的应用程序崩溃了！请帮助我，这里是代码段：

通过你的意图发送它们。
在MainActivityWithButtons中：
Intent i = new Intent(MainActivityWithButtons.this, LocationSelectFromAlertButtons.class);
i.putExtra("some_unique_string1", your_boolean_variable)
startActivity(i);
在LocationSelectFromAlertButtons中，onCreate（）：
boolean your_boolean_variable = getIntent().getBooleanExtra("some_unique_string1", false);

将您的布尔值保存为SharedPreferences的一部分。然后，您可以从应用程序的任何位置访问它。
SharedPreferences preferences = getSharedPreferences(PREFS_NAME, MODE_PRIVATE);
preferences.edit().putBoolean(BOOLEAN_NAME, boolean).apply();
