For input string: ""

Question

Hello Fellows so i have this issue with this android app that i got from github so i could play with it, i don't know now what is causing this

For input string: ""

So here is the build.grable :

apply plugin: 'com.android.application'

def gitCommits = 'git rev-list --all --count'.execute([], 
rootDir).text.trim().toInteger()

def timestamp = new Date().getTime()

android {
compileSdkVersion 28
buildToolsVersion '28.0.3'
defaultConfig {
    applicationId "org.nv95.openmanga"
    minSdkVersion 15
    targetSdkVersion 28
    versionCode gitCommits
    versionName "5.0"

    resConfigs "en", "ru", "tr", "uk"
    buildConfigField "boolean", "SELFUPDATE_ENABLED", "false"
    buildConfigField "String", "SELFUPDATE_URL", "\"http://anibreak.ru/v.0.3/get/openmanga/version\""
    buildConfigField "String", "SYNC_URL", "\"http://openmanga.pythonanywhere.com/api/v1\""
    buildConfigField "long", "TIMESTAMP", "${timestamp}L"
}

signingConfigs {
    debug {
        storeFile file("debug.jks")
        storePassword "develop"
        keyAlias "develop"
        keyPassword "develop"
    }
}

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        setProperty("archivesBaseName", "OpenManga-v${defaultConfig.versionName}")
        resValue "string", "app_name", "OpenManga"
    }

    debug {
        zipAlignEnabled true
        applicationIdSuffix ".debug"
        versionNameSuffix="a"
        signingConfig signingConfigs.debug
        resValue "string", "app_name", "OpenManga Debug"
    }

    fdroid {
        initWith release
        buildConfigField "boolean", "SELFUPDATE_ENABLED", "false"
        versionNameSuffix="-fdroid"
    }
}

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

lintOptions {
    disable 'MissingTranslation'
    abortOnError false
}
}

ext {
supportLib = '28.0.0'
}

dependencies {
implementation "com.android.support:design:${supportLib}"
implementation "com.android.support:support-v4:${supportLib}"
implementation "com.android.support:recyclerview-v7:${supportLib}"
implementation "com.android.support:cardview-v7:${supportLib}"
implementation "com.android.support:exifinterface:${supportLib}"

implementation 'com.squareup.okhttp3:okhttp:3.11.0'
implementation 'com.squareup.duktape:duktape-android:1.3.0'
implementation 'info.guardianproject.netcipher:netcipher:2.0.0-beta1'
implementation 'info.guardianproject.netcipher:netcipher-okhttp3:2.0.0- 
alpha1'
implementation 'org.jsoup:jsoup:1.11.3'
implementation 'com.davemorrissey.labs:subsampling-scale-image-view:3.10.0'
implementation 'com.nostra13.universalimageloader:universal-image- 
loader:1.9.5'
}

After a while of searching and redoing the code i could not solve this issue, i updated my android studio all the dependencies are up to date ( but thats not where the issue is )

This is the error log

What's the beginning of the error? NumberFormatException? Please share the error log... — Nero, Nov 18 '18 at 20:45

If you look carefully at the error log, you'll notice the following error: -

Caused by: java.lang.NumberFormatException: For input string: ""
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)

What you are trying to do here is trying to convert a variable (likely to be a string) into an int but as the variable doesn't contain valid data (but in this case no data at all), it's throwing the error of NumberFormatException. If you click on the NumberFormatException.java link, it will take you straight to the code. Or you can find it yourself at line 65.

To rectify this, I would suggest using Try and catch block, like the following : -

try{
 int myInt = Integer.parseInt(input);
}catch(NumberFormatException ex){
   System.out.println("not a number" + ex);
}

This does not return an Integer value:

def gitCommits = 'git rev-list --all --count'.execute([], rootDir).text.trim().toInteger()

...while versionCode expects an Integer value. Therefore it could only be used as or be appended to the versionName. Or convert from hexadecimal to decimal, to provide an Integer value (I've never tried that, unsure if this would provide values in succession).

The value range of int data in Java is [-2^31, 2^31-1]. That is -2147483648 ~ 2147483647. If the versionCode you defined exceeds this range, NumberFormatException will be thrown. Try to shorten the range of versionCode, for example:

versionCode : Integer. parseInt(new Date(). format("MMddHHmm"))
