android - Activity 类 {.....SplashActivity} 不存在

Question

我在设备上运行项目时遇到这些错误:

Launching application:.Splash_Activity.
DEVICE SHELL COMMAND: am start -n ".Splash_Activity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=.Splash_Activity }
Error type 3
Error: Activity class {.Splash_Activity} does not exist.

我检查我的 Android-Manifest 文件是这样的

 <activity
        android:name=".SplashActivity"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen">

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        
</activity>

Gradle 就像:

apply plugin: 'com.android.library'

android {
    compileSdkVersion 21
    buildToolsVersion "21.0.2"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 21
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
allprojects {
    tasks.withType(JavaCompile) {
        options.compilerArgs << "-Xlint:deprecation" << "-Xlint:unchecked"
    }
}

repositories {
    jcenter()
}


dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:cardview-v7:+'
    compile 'com.google.android.gms:play-services:4.3.+'
    compile files('libs/GraphView-3.1.3.jar')
    compile files('libs/google-play-services.jar')
    compile files('libs/android-support-v4.jar')
    compile files('libs/bolts-android-1.1.2.jar')
    compile 'com.github.navasmdc:MaterialDesign:1.+@aar'
    compile files('libs/nineoldandroids-2.4.0.jar')
    compile 'com.android.support:appcompat-v7:22.0.0'
}

我也通过更改包名称等尝试了很多..我应该怎么做才能解决这个问题？
