Android 应用程序未在牛轧糖中打开

我正在编写一个新的应用程序，并尝试使用不同的版本。当我尝试牛轧糖时，我的应用程序无法打开。它只是说：

应用程序已停止。再次打开应用程序

如果我再次按open，应用程序将一直停止

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"  


    defaultConfig {       
        minSdkVersion 11
        targetSdkVersion 25
        versionCode 1
        versionName "2.0"
        multiDexEnabled true
    }
}

我尝试了BuildToolsVersion25.0.1，但没有。有什么帮助吗

这是我在牛轧糖装置中打开它时的logcat跟踪

编辑：我的清单的权限请求

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.DISABLE_KEYGUARD" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.MANAGE_DOCUMENTS" />

这可能是因为在Nougat Android 7.0中，权限的更改可能会影响你的应用程序。它不是强制执行的，但它会弹出您可能无法处理的异常。您应该阅读以下文档：

并检查这些答案

请包括onCreate方法和MainActivity.java的第175行标记。第175行是我将.txt复制到SDCard中需要使用的地方，因此可能是Tompadre所说的权限问题。很高兴它有所帮助。请检查答案是否正确。干杯
