if a device has an SD card, you use:
如果设备有 SD 卡，您可以使用：
Environment.getExternalStorageState()
if you don't have an SD card, you use:
如果您没有 SD 卡，您可以使用：
Environment.getDataDirectory()
if there is no SD card, you can create your own directory on the device locally.
如果没有SD卡，您可以在本地设备上创建自己的目录。
//if there is no SD card, create new directory objects to make directory on device
if (Environment.getExternalStorageState() == null) {
//create new file directory object
directory = new File(Environment.getDataDirectory()
+ "/RobotiumTestLog/");
photoDirectory = new File(Environment.getDataDirectory()
+ "/Robotium-Screenshots/");
/*
* this checks to see if there are any previous test photo files
* if there are any photos, they are deleted for the sake of
* memory
*/
if (photoDirectory.exists()) {
File[] dirFiles = photoDirectory.listFiles();
if (dirFiles.length != 0) {
for (int ii = 0; ii <= dirFiles.length; ii++) {
dirFiles[ii].delete();
}
}
}
// if no directory exists, create new directory
if (!directory.exists()) {
directory.mkdir();
}
// if phone DOES have sd card
} else if (Environment.getExternalStorageState() != null) {
// search for directory on SD card
directory = new File(Environment.getExternalStorageDirectory()
+ "/RobotiumTestLog/");
photoDirectory = new File(
Environment.getExternalStorageDirectory()
+ "/Robotium-Screenshots/");
if (photoDirectory.exists()) {
File[] dirFiles = photoDirectory.listFiles();
if (dirFiles.length > 0) {
for (int ii = 0; ii < dirFiles.length; ii++) {
dirFiles[ii].delete();
}
dirFiles = null;
}
}
// if no directory exists, create new directory to store test
// results
if (!directory.exists()) {
directory.mkdir();
}
}// end of SD card checking
add permissions on your manifest.xml
在 manifest.xml 上添加权限
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

To find locations on internal storage for your app, use getFilesDir(), called on any Context (such as your Activity, to get a File object.
要为您的应用程序查找内部存储上的位置，请使用getFilesDir()，在任何上下文（例如您的活动）上调用以获取 File 对象。
why can't you use Environment.getExternalStorageDirectory()for getting /storage/sdcard0/ path from code ?
为什么不能使用Environment.getExternalStorageDirectory()从代码中获取 /storage/sdcard0/ 路径？
need to add permissions as well.
还需要添加权限。
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
