Ответ 1
если устройство имеет SD-карту, вы используете:
Environment.getExternalStorageState()
если у вас нет SD-карты, вы используете:
Environment.getDataDirectory()
если нет SD-карты, вы можете создать свой собственный каталог на устройстве локально.
//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
