从AndroidStudio运行时安装APK时应用程序崩溃完美无缺

我最近将Android Studio更新为2.3,将SDK更新为25.现在,当我在我的手机或模拟器上运行Android Studio应用程序时,它运行正常但是当我生成APK或从应用程序获取APK并在设备上安装时会崩溃.

apply plugin: 'com.android.application'
    android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
    applicationId "lovestar.lycamobile"
    minSdkVersion 15
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.2.0'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'

}
