当手动添加Apk文件时，它会崩溃

Question

当我在Android Studio中运行我的项目时，它在usb连接时在设备上运行正常。但是，当我解压缩apk并手动将其安装到设备时，我的第二个活动崩溃了。可能是什么原因？

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.figengungor.gazeteler"
        minSdkVersion 9
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'
    compile 'com.android.support:recyclerview-v7:21.0.+'
    compile 'com.android.support:support-v4:21.0.3'
    compile 'com.squareup.picasso:picasso:2.5.0'
    compile 'org.jsoup:jsoup:1.7.3'
    compile files('libs/commons-lang-2.6.jar')
    compile project(':sweetalert')

logcat的：
