Hello everyone, how are you?
Could someone please help me with this problem? I had the M64Plus FZ on my old TV with Android 9 and the emulator worked normally. Recently I bought a TV with Android 12 and it doesn’t allow me to add the ROM files, nor the folder where they are located. I get the following error: YOU DON’T HAVE AN APP TO DO THIS.
Thank you in advance for your attention.
I’ve been unplugged from this project for a few years since I handed it over to @fzurita when I re-focused my time to other topics (AI then, and now Bitcoin). Your best bet will probably be to open an Issue for this (if there is not already one) on the Github repo.
I did a quick search through the code, though, and I can see where the problem is likely going to be located (though the current devs will need to confirm).
The error message “You don’t have an app to do this” occurs when Android cannot find an app to handle the Storage Access Framework (SAF) intents (ACTION_OPEN_DOCUMENT_TREE in AppData.java around line 409 and ACTION_OPEN_DOCUMENT in DataPrefsActivity.java around line 258).
In AppData.java, the app determines whether to use the legacy file browser. It checks if ACTION_OPEN_DOCUMENT_TREE can be resolved. Most likely, on Android TV 12, there isn’t a default system file picker app installed that can handle these SAF intents, causing resolveActivity() to return null.
It looks like this check attempts to fall back to the legacy file browser when SAF isn’t available, so there may be a timing or configuration issue, Some possibilities:
<queries> element in AndroidManifest.xml (around line40) might be interfering with the detectionMy guess, without digging into this too deeply, is that Andoroid 12 could have interfered with this feature due to more restrictive package visibility rules or not having a pre-installed file manager app.
The devs will probably need to take a look at the detection logic in the resolveActivity() to see if changes are needed for Android 12 in certain scenarios. In the mean time, you might try installing a file manager app from the Play store and see if it resolves the problem for you. Some potential examples:
