Android runtime error with release version but not debug version

Question

The following error is occurring when running the release version of my app, but not the debug version:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.cloud3squared.meteogram/com.cloud3squared.meteogram.Meteogram}: android.content.res.Resources$NotFoundException: String resource ID #0x7f0901e4

Any ideas why? I have my suspicion that it may have something to do with the fact that I'm using BuildConfig values in my code, and there is at least one suggestion that such values are not being generated in the release version, but I've tried changing BuildConfig.VERSION_NAME in the following to a straight string value, and still it crashes.

((TextView) findViewById(R.id.app_version)).setText(BuildConfig.VERSION_NAME);

I also make use of buildConfigField in my build.gradle:

buildConfigField "String", "APP_TYPE", "\"devfree\""

which I access all over the place as BuildConfig.APP_TYPE.

Incidentally, this issue (crashing with release but but debug version) only started happening when I updated everything I could in my build.gradle files to the latest versions, e.g.

app-level:

buildToolsVersion "23.0.1"
compileSdkVersion 23
defaultConfig {
    targetSdkVersion 23
}

top-level:

dependencies {
    classpath 'com.android.tools.build:gradle:1.3.0'
}

Before that (and if I revert to older versions), it was/is all fine.

EDIT... to answer the comment below, here is my complete app-level build.gradle file:

android {
    signingConfigs {
        development {
            keyAlias 'xxx'
            keyPassword 'yyy'
            storeFile file('C:/Users/xxx/yyy.jks')
            storePassword 'zzz'
        }
    }
    compileSdkVersion 23
    buildToolsVersion "23.0.1"
    defaultConfig {
        applicationId "com.cloud3squared.meteogram"
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 144
        versionName "1.7.14"
        signingConfig signingConfigs.development
    }
    productFlavors {
        pro {
            applicationId "com.cloud3squared.meteogram.pro"
            buildConfigField "String", "APP_TYPE", "\"pro\""
        }
        free {
            applicationId "com.cloud3squared.meteogram"
            buildConfigField "String", "APP_TYPE", "\"free\""
        }
        devpro {
            applicationId "com.cloud3squared.meteogram.devpro"
            buildConfigField "String", "APP_TYPE", "\"devpro\""
        }
        devfree {
            applicationId "com.cloud3squared.meteogram.devfree"
            buildConfigField "String", "APP_TYPE", "\"devfree\""
        }
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

repositories { mavenCentral() }

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.android.gms:play-services-location:8.1.0'
    compile project(':ambilwarna')
    compile 'com.facebook.android:facebook-android-sdk:4.7.0'
    compile project(':devmilColor')
    compile 'com.google.guava:guava:18.0'
}

Answer 1

Try to clean and build the project. That should fix the issue
