Release Mode Build 😞 💥

[onuryurtturk]

How to build project for signed apk?. When I generate signed apk. It doesnt install on device. Im thinking about this is occurring because the library didn't build for release. How can i build for release mode?

Library has only debug build version, but it works in release build types. Maybe you forgot add rules to proguard?

-keep class org.beyka.tiffbitmapfactory.**{ *; }

If with proguard all ok, please provide you build.gradle file(build and flavour type sectoin)

I dont use proguard but added that line. Not working. Release apk not install on device. Any solution?

` apply plugin: 'com.android.application'

android { compileSdkVersion 25 buildToolsVersion "25.0.2"

defaultConfig {
    applicationId "xyz"
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    multiDexEnabled true

}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

/* splits {

    // Configures multiple APKs based on ABI.
    abi {

        // Enables building multiple APKs per ABI.
        enable true

        // By default all ABIs are included, so use reset() and include to specify that we only
        // want APKs for x86, armeabi-v7a, and mips.

        // Resets the list of ABIs that Gradle should create APKs for to none.
        reset()

        // Specifies a list of ABIs that Gradle should create APKs for.
        include "x86", "armeabi-v7a", "mips" , 'armeabi'

        // Specifies that we do not want to also generate a universal APK that includes all ABIs.
        universalApk false
    }
}*/

}

// Map for the version code that gives each ABI a value. ext.abiCodes = ['armeabi':1, 'armeabi-v7a':2, mips:3, x86:4]

// For per-density APKs, create a similar map like this: // ext.densityCodes = ['mdpi': 1, 'hdpi': 2, 'xhdpi': 3]

import com.android.build.OutputFile

// For each APK output variant, override versionCode with a combination of // ext.abiCodes * 1000 + variant.versionCode. In this example, variant.versionCode // is equal to defaultConfig.versionCode. If you configure product flavors that // define their own versionCode, variant.versionCode uses that value instead. android.applicationVariants.all { variant ->

// Assigns a different version code for each output APK
// other than the universal APK.
variant.outputs.each { output ->

    // Stores the value of ext.abiCodes that is associated with the ABI for this variant.
    def baseAbiVersionCode =
            // Determines the ABI for this variant and returns the mapped value.
            project.ext.abiCodes.get(output.getFilter(OutputFile.ABI))

    // Because abiCodes.get() returns null for ABIs that are not mapped by ext.abiCodes,
    // the following code does not override the version code for universal APKs.
    // However, because we want universal APKs to have the lowest version code,
    // this outcome is desirable.
    if (baseAbiVersionCode != null) {

        // Assigns the new version code to versionCodeOverride, which changes the version code
        // for only the output APK, not for the variant itself. Skipping this step simply
        // causes Gradle to use the value of variant.versionCode for the APK.
        output.versionCodeOverride =
                baseAbiVersionCode * 1000 + variant.versionCode
    }
}

Only option that I never try with lib is multiDexEnabled. Could you try to remove that option and test build? Thank you
