Error trying to run APP #96

Open andrefvneto opened 2 years ago

andrefvneto commented 2 years ago

Hi, since Jcenter is down i had problems trying to run my app. First it was asking about paperdb:2.6. Since i was unable to implment that library i've change my implementation of Printooth. So i updated my Printooth to 1.3.1(i am not using androix) Now it returns this error: `Execution failed for task ':app:preDebugBuild'.

Could not resolve all files for configuration ':app:debugRuntimeClasspath'. Could not find com.android.support:design:31.0.0. Searched in the following locations:

Possible solution:

Couldn't find nothing online about com.android.support:design:31.0.0. Any suggestions? I'm really trying not to update to androidx, Thanks

GithubPranshul commented 2 years ago

did you find the solution?

andrefvneto commented 2 years ago

Hi, i belive it was this line that i had to change implementation 'com.github.mazenrashed:Printooth:1.2.1'

About paperdb i found a project (Paper-2.6) and i belive that i've imported the libraries directly into my project. It was some time ago.. sorry

GithubPranshul commented 2 years ago

oh, ok no problem thank you!

matej-dostal commented 1 year ago

Hi, I ran into the same issue now and I just can't fix it. I get the same error message and have no idea why. Could you please give me a hint or some idea on how to fix this? Thanks!

andrefvneto commented 1 year ago

Hi, can you please post the error/log? Thanks

matej-dostal commented 1 year ago

Sure, here it is, this is logged when I try to build the app:

Could not resolve all files for configuration ':app:debugRuntimeClasspath'.

I have it like this: `repositories { mavenLocal() google() mavenCentral() maven { url 'https://www.jitpack.io' } maven { url "https://maven.google.com/" } jcenter()

} Dependecies: implementation 'com.github.mazenrashed:Printooth:1.2.1'`

matej-dostal commented 1 year ago

When I use 1.2.1 version and have it like you do, manifest merger fails, because the rest of the app supports androidx, whereas v1.2.1 doesn't. So when I use v1.3.1 of Printooth, the same errors shows up again as I posted earlier.

@matej-dostal Hi did you fix the error? Even I am facing the same issue, can you please share the solution if you have got it

matej-dostal commented 1 year ago

@matej-dostal Hi did you fix the error? Even I am facing the same issue, can you please share the solution if you have got it

Hi! I did fix it, but to be honest I don't remember exactly how. Could you share both your build.gradle files as well as settings.gradle? It was in one of those files that fixed it so I will have a look at it :)

Okay, so the only difference that I found when compared with my .gradle files is in kotlinOptions, I have it like this: kotlinOptions { jvmTarget = '1.8' freeCompilerArgs += [ '-Xjvm-default=enable' ] }. So give it a try and let me know if that wasn't the solution, I'll keep looking :)

@matej-dostal I'm still getting the same error even after adding the above line of code in the kotlinOptions, can you please help me solve this further

I just realised one more thing, could you post gradle.properties as well, please?

gaara40 commented 1 year ago

Yeah, sure here is the gradlde.properties file

Project-wide Gradle settings.

IDE (e.g. Android Studio) users:

Gradle settings configured through the IDE will override

any settings specified in this file.

For more details on how to configure your build environment visit

http://www.gradle.org/docs/current/userguide/build_environment.html

Specifies the JVM arguments used for the daemon process.

The setting is particularly useful for tweaking memory settings.

org.gradle.jvmargs=-Xmx2048m -Dfile.encoding=UTF-8

When configured, Gradle will run in incubating parallel mode.

This option should only be used with decoupled projects. More details, visit

http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects

org.gradle.parallel=true

AndroidX package structure to make it clearer which packages are bundled with the

Android operating system, and which are packaged with your app's APK

https://developer.android.com/topic/libraries/support-library/androidx-rn

android.useAndroidX=true

Kotlin code style for this project: "official" or "obsolete":

kotlin.code.style=official

Enables namespacing of each library's R class so that its R class includes only the

resources declared in the library itself and none from the library's dependencies,

thereby reducing the size of the R class for that library

android.nonTransitiveRClass=true

@gaara40 do you have bluetooth on your device turned on, your bluetooth printer turned on and paired with the device?

gaara40 commented 1 year ago

yes the bluetooth printer is turned on and is paired to my android device and the Bluetooth is also turned on in my android device

matej-dostal commented 1 year ago

yes the bluetooth printer is turned on and is paired to my android device and the Bluetooth is also turned on in my android device

And does your app have required permissions from user given in runtime? Without that I think you won't make it work.

gaara40 commented 1 year ago

yes, the permissions are also granted

matej-dostal commented 1 year ago

I have these permissions required in runtime (also specified in manifest) and it works fine:

gaara40 commented 1 year ago

I had these permissions in manifest, I figured out the code now and it worked thankyou so much @matej-dostal for helping me out. There is something more I need to know, can we print custom texts like if we enter a name or a number in the edittext fields and click the print button the name and the number gets printed?

No problem, I'm happy to help :) Sure thing we can, just build the printable, you send to the printer, dynamically and fill it with the input from user :)

gaara40 commented 1 year ago

Got it, Thank you very much @matej-dostal for your guidance, I don't know where would I be without your help, I am trying this since 3 weeks, finally got it done.

matej-dostal commented 1 year ago

No problem, good luck coding the rest of the app :) @gaara40

gaara40 commented 1 year ago

my app runs only when i explicitly allow the nearby devices permission, otherwise the app crashes when I click the print button, any solutions??? tried the onrequestpermission but still not working.....

andrefvneto commented 1 year ago

Hi, can you try this: Since android 12, you need to runtime ask for the permission if (ContextCompat.checkSelfPermission(this, Manifest.permission.BLUETOOTH_CONNECT) != PackageManager.PERMISSION_GRANTED) {

        // Caso a permissão ainda não tenha sido concedida, solicita ao usuário
        ActivityCompat.requestPermissions(this,
                new String[]{Manifest.permission.BLUETOOTH_CONNECT},
                4444);
    } else{
        //has permisson, your code logic

BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); if (!mBluetoothAdapter.isEnabled()) { Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE); startActivityForResult(enableBtIntent, 1);

        }
    }

@Override public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { super.onRequestPermissionsResult(requestCode, permissions, grantResults); if (requestCode == 4444) { if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { // GRANTED } else { //DECLINED } } }

Dont forget to add to the manifest "BLUETOOTH_CONNECT" permission

gaara40 commented 1 year ago

still not working

andrefvneto commented 1 year ago

can you give more detail? when the app crashes what kind of error it returns?

gaara40 commented 1 year ago

java.lang.SecurityException: Need android.permission.BLUETOOTH_SCAN permission for AttributionSource....... this is the error I am having, yet after declaring the permission in the manifest file

andrefvneto commented 1 year ago

i have this on my manifest: ` 

<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />
<uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
<uses-permission android:name="android.permission.BLUETOOTH_ADVERTISE" />`
gaara40 commented 1 year ago

what about runtime permissions, how do i ask for runtime permissions, do you have any simple way where I can learn how to use them?

andrefvneto commented 1 year ago

ask for this as well: String[] permissions = {Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION, for(int i=0;i<permissions.length-1;i++){

                if (ContextCompat.checkSelfPermission(MainActivity.this, permissions[i]) == PackageManager.PERMISSION_GRANTED) {

                } else {
                    ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION,
                            Manifest.permission.ACCESS_COARSE_LOCATION,

                            Manifest.permission.CAMERA}, PackageManager.GET_PERMISSIONS);

                }

}
