Release version works but APK release doesnt work. #481

JayadevHaddadi · 2020-11-04T10:35:03Z

I'm using latest version of Flutter 1.22.3 and Android Studio 4.1. Flutter doctor has no issues.
Latest version of FilePicker 2.0.11.

When I run the app as debug or release version is fine.
But the APK release when installed crashes immediately. I can not get any reports even when I turn on debuggable for release.
Crash disappears as soon as I disable file_picker.

I appreciate any help.

miguelpruivo · 2020-11-04T11:56:34Z

@JayadevHaddadi try using adb logcat and check what's happening when it crashes.

Add following code to your proguard file.

-keep class androidx.lifecycle.** { *; }

yoseptara · 2020-11-05T09:22:11Z

Add following code to your proguard file.
-keep class androidx.lifecycle.** { *; }

First of all check you Android Grudle version in the android/build.gradle file.

Find this line: classpath 'com.android.tools.build:gradle:X.X.X' - Gradle >= 4.0.0 plugin does not work correctly!

Change to:
classpath 'com.android.tools.build:gradle:3.5.3'

Information about Gradle 4.0.0:
flutter/flutter#58247

hamberluo · 2020-11-06T02:38:13Z

Add following code to your proguard file.
-keep class androidx.lifecycle.** { *; }
where can i find this file sir?

You can create proguard-app.pro and use proguardFiles 'proguard-app.pro'

miguelpruivo · 2020-11-06T11:33:09Z

@AleksMx have you managed to fix it?

AleksMx · 2020-11-06T12:14:42Z

@AleksMx have you managed to fix it?

Yes. It is necessary to downgrade the Gradle plugin version to 3.

miguelpruivo · 2020-11-06T15:01:03Z

@JayadevHaddadi could you please try the suggested fix?

JayadevHaddadi · 2020-11-07T08:14:59Z

Thanks for the prompt help.

I changed from 4.0.0 to:
classpath 'com.android.tools.build:gradle:3.5.3'
Then I get this error.

`FAILURE: Build failed with an exception.

What went wrong:

The second error I could remove by adding the local.properties file they ask for.

:(

Thanks

miguelpruivo · 2020-11-09T22:17:47Z

@JayadevHaddadi could you try checking Android X migration guide and see if it works for you afterwards? Likely to be some incompatibility issue related with it.

chris-profico · 2020-11-10T03:58:35Z

The problem has been solved on my side.
By following the recommendations of @miguelpruivo, and I am very grateful to him.

What I have done:

I open my project's Android folder via AndroidStudio and run "Sync Project with Gradle Files"

Note: Under AndroidStudio 4.1 you have to open the Android folder of the project and not the project itself to see the “Sync Project with Gradle Files” tool appear (half an hour to find this)

AndroidStudio kindly offers to update Gradle, which I did (in my case, 3.5.0 to 4.1.0)
I select “Migrate to AndroidX” from Refactor menu… -> Do Refactor
I change the values of “compileSdkVersion” and “targetSdkVersion” to 29 in pubspec.yaml

Problem solved!

JayadevHaddadi · 2020-11-10T07:49:34Z

I tried whatever @miguelpruivo said and also @chris-pro.
I update gradle to 4.1.
I open Android folder as project in AS, i synced etc.
I refactored to AndroidX.
I tried with SDK 30 and 29 also (I think you meant gradle file @chris-pro)
The app starts but gets stuck on the first screen as APK version. While the normal release/debug version works fine.
:(

miguelpruivo · 2020-11-10T10:32:52Z

@JayadevHaddadi could that be related with something else on your app? Since the app runs anyway.

The easiest is to re-create an empty flutter project. Then copy the lib folder into it from you old project. What you do can lead to undefined behavior.

Small correction on my previous post.

My application was working fine in debug mode on the emulator but there were some complications when I wanted to do an app-release.

The issue was related to Gradle version 4 as reported by @AleksMx.
So I downgraded Gradle to version 3.6.3
Now the application now works correctly in debug and release mode.

To summarize the changes that fixed the problem:

Before

android/app/build.gradle

compileSdkVersion 28
targetSdkVersion 28

android/build.gradle

classpath 'com.android.tools.build:gradle:3.5.0'

android/gradle/wrapper/gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.2-all.zip

After

android/app/build.gradle

compileSdkVersion 29
targetSdkVersion 29

android/build.gradle

classpath 'com.android.tools.build:gradle:3.6.3'

android/gradle/wrapper/gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-all.zip

JayadevHaddadi · 2020-11-11T07:00:54Z

@chris-pro
This finally worked!:))
So happy. Thanks.
I updated those values exactly as prescribed and it worked...
Thanks:)
Thank you @miguelpruivo and @AleksMx

miguelpruivo · 2020-11-11T10:00:36Z

Thank you for your clear explanation @chris-pro! 👌

Closing as it is now resolved.

Sorry but this does not work for me, I followed proguard and gradle advices, yet it crashes when users picks pdf on release mode.
Strangely enough it goes well on debug.

pierre-gancel · 2021-03-11T17:21:48Z

Here is a snippet

FilePickerResult result = await FilePicker.platform.pickFiles(
          allowMultiple: false,
          type: FileType.custom,
          allowedExtensions: ['pdf']);
      if (result != null) {
        File file = File(result.files.single.path);
        //print("nikfilename${file.path.substring(file.path.lastIndexOf("/"))}");
        setState(() => pickedPdfFile = file);
      }
