文件没问题的情况下not read packageName from xxx\AndroidManifest.xml？

Question

之前没问题的项目打开之后Gradle报错：

Try Again以后还是不行，Messages显示如下：

仔细检查没有发现问题，最后新建一个工程把文件挨个拷贝，新工程一切正常，想知道遇到这种问题如何解决，不能总是新建工程吧。最后附上还是有问题的老工程AndroidManifest文件：

代码排版好像有点问题，请见谅。
补充app下gradle文件：

apply plugin: 'com.android.library'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.0"
    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        applicationId "com.kunpo.loner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    useLibrary 'org.apache.http.legacy'
}

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-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    provided files('libs/classes.jar')
    compile 'org.apache.httpcomponents:httpcore:4.4.2'
    compile files('libs/alipaySdk-20170407.jar')
    compile files('libs/wechat-sdk-android-without-mta-1.1.6.jar')
}

工程根目录gradle文件：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

你看看你的gradle里面有 applicationId 吗？ 如果没有的话加上应该就可以了
