如何在Robotium中创建屏幕截图

Question

我想知道如何在Robotium的AVD上截屏。 我已经读过1st我必须具有权限，但是我已经做到了。

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_INTERNAL_STORAGE" />

但是我在Android Monitor上还是有错误

D/Robotium: Can't save the screenshot! Requires write permission (android.permission.WRITE_EXTERNAL_STORAGE) in AndroidManifest.xml of the application under test.
W/System.err: java.io.FileNotFoundException: /sdcard/Screenshot/asd.jpg: open failed: EACCES (Permission denied)

我手动创建目录以确保该目录存在。

我也试图在磁盘上截屏

String path = "/sdcard/SS";
solo.getConfig().screenshotSavePath = path;
solo.takeScreenshot("asd");

path = "C:/";
solo.getConfig().screenshotSavePath = path;
solo.takeScreenshot("asd");

但是错误仍然存​​在。 截屏有什么问题？

Answer 1

如果您已经创建了SS目录：

String path = Environment.getExternalStorageDirectory().getPath() + "/SS";

Answer 2

首先，按照@Seishin所说的那样创建路径：

String path = Environment.getExternalStorageDirectory().getPath() + "/SS";

然后，转到build.gradle文件，并将targetSdkVersion降级为22 。

高于22 ，我的意思是： 23或24 ，需要定义Android Permissions Control，这与仅定义以下内容有所不同：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

阅读： https : //developer.android.com/training/permissions/index.html

这些权限（运行时权限）适用于Android 6.0及更高版本，所需的代码如下所示：

// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
                Manifest.permission.READ_CONTACTS)
        != PackageManager.PERMISSION_GRANTED) {

    // Should we show an explanation?
    if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
            Manifest.permission.READ_CONTACTS)) {

        // Show an expanation to the user *asynchronously* -- don't block
        // this thread waiting for the user's response! After the user
        // sees the explanation, try again to request the permission.

    } else {

        // No explanation needed, we can request the permission.

        ActivityCompat.requestPermissions(thisActivity,
                new String[]{Manifest.permission.READ_CONTACTS},
                MY_PERMISSIONS_REQUEST_READ_CONTACTS);

        // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
        // app-defined int constant. The callback method gets the
        // result of the request.
    }
}

为了避免这种情况，只需将targetSdkVersion降级。

希望对你有帮助
