Java – the file was not found when trying to compile the telegraph source code

I'm trying to build an application like telegraph I downloaded their source code（ https://github.com/DrKLO/Telegram ）(for Android)

My main problem is that when I try to compile the code and export it to my phone, I find this error using Android Studio:

Error: the configuration problem of task ': tmessagesproj: packagedebug' was found

Obviously, the file is missing, but which, how can I solve this problem?

thank you!

PS: can you give me a link to the source code of an application similar to this or WhatsApp?

Solution

Change telegraph / tmessagesproj / build Gradle and delete or comment on the signature options in the gradle configuration as follows:

apply plugin: 'com.android.application'

repositories {
    mavenCentral()
}

dependencies {
    compile 'com.android.support:support-v4:22.2.+'
    compile 'com.google.android.gms:play-services:3.2.+'
    compile 'net.hockeyapp.android:HockeySDK:3.5.+'
    compile 'com.googlecode.mp4parser:isoparser:1.0.+'
}

android {
    compileSdkVersion 22
    buildToolsVersion '22.0.1'

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
/**
    signingConfigs {
        debug {
            storeFile file("config/debug.keystore")
        }

        release {
            storeFile file("config/release.keystore")
            storePassword RELEASE_STORE_PASSWORD
            keyAlias RELEASE_KEY_ALIAS
            keyPassword RELEASE_KEY_PASSWORD
        }
    }
*/
    buildTypes {
        debug {
            debuggable true
            jniDebuggable true
           // signingConfig signingConfigs.debug
        }

        release {
            debuggable false
            jniDebuggable false
            //signingConfig signingConfigs.release
        }

        foss {
            debuggable false
            jniDebuggable false
           // signingConfig signingConfigs.release
        }
    }

    sourceSets.main {
        jniLibs.srcDir 'libs'
        jni.srcDirs = [] //disable automatic ndk-build call
    }

    sourceSets.debug {
        manifest.srcFile 'config/debug/AndroidManifest.xml'
    }

    sourceSets.release {
        manifest.srcFile 'config/release/AndroidManifest.xml'
    }

    sourceSets.foss {
        manifest.srcFile 'config/foss/AndroidManifest.xml'
    }

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 22
        versionCode 572
        versionName "3.0.1"
    }
}
