Android ActivityCompat类没有requestPermission方法。

最近将我的Android Studio更新为2.3.2，自更新后，我无法在手机上运行该项目。首先，它在gradle构建期间不会显示任何错误。但是当你在手机上运行它时，它会给出以下错误

找不到ActivityCompat中的方法requestPermission。我尝试单击ActivityCompat检查源代码，但其中没有requestPermission方法。事实上，ActivityCompat中只有两种方法

这是给出错误的requestPermission的用法。这是在活动中调用的，而不是在片段中调用的

if (ContextCompat.checkSelfPermission(getBaseContext(),
                                android.Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
                            ActivityCompat.requestPermissions(this,
                                    new String[]{android.Manifest.permission.READ_EXTERNAL_STORAGE,
                                            android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, GALLERY_ACTIVITY_CODE);
                        } else {
                            chooseGalleryImage();
                        }

可能是“即时跑步”的问题。尝试从首选项中禁用它，然后查看结果。或者执行干净的构建。@Milanix我尝试禁用即时运行，清理项目，然后运行它。它仍然给出相同的错误。我完全不知所措。最有趣的是，当我打开ActivityCompat时，它只显示其中的这两个方法-InvalidateOptions功能表和startActivities.code>ActivityCompat是否来自

android.support.v4.app.ActivityCompat

可通过gradle

编译'com.android.support:support-v4:25.2.0'

@k3b嘿，我不确定。ActivityCompat的软件包显示android.support.v4.app。我怎样才能知道它是从哪个包裹取走的？我删除了support-v4依赖项，它在ActivityCompat上没有显示错误。我看到了类似的问题。我已经更改了依赖项中带有“compile”的行的顺序。---工作：compile'com.android.support:appcompat-v7:25.3.1'compile'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.0.2'compile'org.eclipse.paho:org.eclipse.paho.android.service:1.0.2'----不工作：compile'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.0.2'compile'org.eclipse.paho:org.eclipse.paho.android.service:1.0.2'编译'com.android.support:appcompat-v7:25.3.1'——因此可能有一些依赖项。
