App built in release mode does not start

[novemberisms]

My app built in release mode does not get past the launch screen. When built in debug mode, everything works fine.

In my main method, I have the following code that will check if a previous login session exists so the user does not need to log in again each time.

Future<null> main(List<String> args) async {
    // ...
    final storage = FlutterSecureStorage();
    final hasExisting = await storage.read(key: "isExisting");
    // ...
    runApp(MyApp(hasExisting: hasExisting));
}

And I can confirm that this plugin is the one causing the problem because when I change the code to the following

Future<null> main(List<String> args) async {
    // ...
    // final storage = FlutterSecureStorage();
    // final hasExisting = await storage.read(key: "isExisting");
    final hasExisting = false;
    // ...
    runApp(MyApp(hasExisting: hasExisting));
}

Everything works, but of course the desired function is not the same.

I can confirm it was working as of March 5, but it no longer does.

Having the same Problem, but not only with release, also in "debug". One major thing i can remember is, that i updated the toolchain to (Android toolchain - develop for Android devices (Android SDK version 28.0.3) very recently and not much else.

Unhandled Exception: PlatformException(error, Unsupported value: javax.crypto.BadPaddingException: error:1e000065:Cipher functions:OPENSSL_internal:BAD_DECRYPT, null)

[daniel-mf]

I fixed this issue by executing await storage.deleteAll(); only once, after setting backups off:

<application
        ...
            android:allowBackup="false"
            android:fullBackupContent="false">

[pythoneer]

@daniel-mf at some point i added those attributes to the application tag but it was days after that the error occurred. Unfortunately the device which was affected (Nexus 6P) died a couple of days (bootloop). So is your suggestion to just make that call once after app installation or do you think this is triggered after a change to those attributes and i should call deleteAll in apps when i change this after those are initially released and/or don't bother if i started with those attributes in the first place. To be honest i can't really understand how those have any effect in regard to the problem. Do you have an idea?

[daniel-mf]

@pythoneer Sorry, I can't tell exactly what happened. I was getting the error, then I added the backup off attributes. Still same error. I thought that maybe the backup had already being done so I might need to delete it all. I executed deleteAll and it worked. Maybe something else happened, maybe unrelated, sorry. Perhaps you could try executing it every first time launch.

[sccrgoalie1]

I was having the same problem as above. The easy fix for me was to clear storage for the app.

Settings -> Apps -> Your App -> Storage -> Clear Storage

[pythoneer]

What is still unclear to me is, if this is happening "in the wild" or has something to do with development. Because on one of my new devices i am developing on this was happening again. But i am unable to reproduce it. It just suddenly happened. But i can imagine it has something to do with rapid deployment where the app is starting and all of the sudden a new version is deployed right in between where something with the en/decryption is happening and some keys get only stored half way because the app is restarting/redeploying. It never occurred on devices that are there only for testing not developing.

One thing i do now is to make a "fake" call to the storage (read some useless key) at the start of the application and .deleteAll() if an exception is thrown. This would potentially delete all the user data, but it is better than the other way, because the app is unusable if this happens. We "just" store credentials inside it, that could easily be reentered – its just for convenience. But its still unfortunate because i don't know if our client plans to use it for something else in the future.

[mogol]

Do you see in logs this record?

                Log.e("StorageCipher18Impl", "unwrap key failed", e);

[Henawey]

this issue almost year and half old, I'm not sure if there is a plan to fix it soon

[ATemirlan]

Had the same issue. Fixed by adding TimeOutException. Inside LoginPage or in catch block delete all storage.

StatefulWidget homeScreen;

try {
    final token =
        await Application.getToken().timeout(const Duration(seconds: 2));
    homeScreen = token != null ? TabControllerPage() : LoginPage();
  } catch (e) {
    homeScreen = LoginPage();
  }

runApp(App(homeScreen));

[karolinaoparczyk]

I have a similar issue. After installing .apk file and launching application on a device, it uses FlutterSecureStorage to get information if user is logged in or not, along with other values. I expect null during first run, of course, but storage.read(key) seams to fail before returning any value.

Added backup tags in main/AndroidManifest.xml

<application
       ...
        android:allowBackup="false"
        android:fullBackupContent="false">

Added deleting keys on startup

final FlutterSecureStorage storage = FlutterSecureStorage();

Future<void> checkIfUserIsSignedIn() async {
    storage.deleteAll();

    try{
      isUserSignedIn = await storage.read(key: _isLoggedIn);
    }
    catch (e){
      print(e);
    }
    setState(() {});
  }

Tried with FlutterSecureStorage v.3.3.3 and FlutterSecureStorage v.3.2.0, but there was no change. I checked SDK version of my device (Honor 10) - 29. Also checked on other device (Samsung Galaxy S9+), but the issue also occurs.

Running flutter run --release causes warnings:

I tried to make sure my project is migrated to AndroidX and got a message: No Usages Found in the Project.

I don't have any more ideas, could you help me?

[karolinaoparczyk]

I tried using SharedPreferencesas a temporary workaround, but it still didn't work - as I guess, the package was not initialized.

I built my app withflutter build apk --release --no-shrink after reading this thread https://github.com/flutter/flutter/issues/65334.

Then tried flutter build apk --release --no-shrink with the version of my application that uses FlutterSecureStorageand it worked.

Should I really consider it as a valid fix and always build my application this way?

Can everyone that is having this issue make sure they are using embedding v2 on their application. Also please comment the output of flutter doctor -v and make sure that you are using the latest version of this plugin, v4.2.1.

I'm closing this for now due to no activity. If anyone still has this issue, feel free to comment.

@juliansteenbakker I am also facing problem of PlatformException when I am downloading installing aab from market. Yes, the clear storage do the thing, but that's incorrect behavior. Huawei Mate 20 light.

faced issue with :

ax.crypto.BadPaddingException: error:1e000065:Cipher functions:OPENSSL_internal:BAD_DECRYPT

on Android 13 when building the app in release mode. Fixed by adding it to the manifest.

<application

            android:allowBackup="false"
            android:fullBackupContent="false">

I have been receiving this error as well:

PlatformException (Exception encountered, write, java.lang.NullPointerException: Attempt to invoke interface method 'byte[] a5.i.a (bytel]) on a null object reference at z4.a.p (Unknown Source:24) at z4.e$b.run (Unknown Source:278) at android.os.Handler.handleCallback(Handler.java:969) at android.os.Handler.dispatchMessage(Handler.java:100) at android.os.Looper.loopOnce(Looper.java:201) at android.os.Looper.loop(Looper.java:288) at android.os.HandlerThread.run (HandlerThread.java:67) , null) 1

I have not being able to figure out what it is. Our app is already live and this only occurs for a specific android tablet called 'Blackview Tab 30 WiFi'. Last time I faced something similar called 'BadPaddingException' it was again on a specific android tablet. In general I have not being able to reproduce this error on any other physical device or emulators. We had managed to fix the BadPaddingException by telling the customer to do a factory reset and it worked. This is not ideal I know. Note that we did the same to this guy with the Blackview tablet but this did not fix it this time. The error happened during login phase in both cases.

I haven't been able to find much on the issue, right now I am just trying to add null checks everywhere during login phase. I am a junior dev.
