我已经将我的项目存储在DropBox中以便在计算机之间共享,因此我可以在楼上的笔记本电脑上工作。一切都在我的电脑上工作正常,然后我去了我的笔记本电脑上加载项目,当我试图运行它时它就崩溃了所以我放弃了并回到我的电脑上,但现在它也没有在那里工作。它工作正常,我根本没有改变任何代码。但现在我得到以下错误。
无论有多少gradle同步和更新以及我尝试的所有内容,我都无法弄清楚如何修复。除了解决这个问题之外,我怎么能在多台PC上同一个项目上工作而不打破一切?
我跑了一个Gradle Clean和Sync,但它似乎也没那么奏效。我也没有意识到我正在使用AsyncTask,所以我会看一下。
由于我不确定堆栈跟踪究竟是什么,这里是我的整个LogCat:)

答案 0 :(得分:0)
首先,在这个项目最后工作的原始计算机上,尝试使用gradle“clean”然后构建。如果这不起作用,可能意味着您上次工作后更改了代码。试着找出你改变了什么,然后撤消它。
其次,AsyncTask是许多令人头疼(和崩溃)的根源,因为它拥有对其启动的Activity的引用,但不是Activity的生命周期的一部分,因此可以在Activity之后对Activity进行操作活动已被破坏。我的建议 - 不要使用AsyncTask - 无论你使用它是什么,几乎总有一种更好的方法。在这里发布您的堆栈跟踪,我们可以帮助您找出问题所在。
就共享代码而言,使用版本控制系统。 GitHub很好,它是免费的。正确使用它还可以让您轻松地将代码回滚到最后一次工作的位置。

好的,看看你从logcat发布的堆栈跟踪,我们看到了:
java.lang.RuntimeException:执行doInBackground()时发生错误 在android.os.AsyncTask $ 3.done(AsyncTask.java:309)java.util.concurrent.FutureTask.finishCompletion(FutureTask.java:354)at java.util.concurrent.FutureTask.setException(FutureTask.java:223) at java.util.concurrent.FutureTask.run(FutureTask.java:242)at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1113)at java.util.concurrent.ThreadPoolExecutor $ Worker.run(ThreadPoolExecutor.java) :588)在java.lang.Thread.run(Thread.java:818)
引起: java.lang.SecurityException:权限拒绝:从ProcessRecord打开提供程序com.android.providers.contacts.ContactsProvider2 {36fd80a 4830:com.mydomain.myapp / u0a17}(pid = 4830,uid = 10017)需要android.permission.READ_CONTACTS或android.permission.WRITE_CONTACTS
因此,您似乎正在尝试访问ContactsProvider,但尚未在清单中放置READ_CONTACTS权限。
