一、内容读取所需jar包导入
异常崩溃点1 ：以下异常均为jar包未导全
1、java.lang.NoClassDefFoundError: Failed resolution of: Ljavax/xml/stream/XMLStreamReader;
2、RuntimeException异常 ：无法正确读取文本内容
3、org.xml.sax.SAXNotRecognizedException: http://xml.org/sax/properties/declaration-handler

二、Android studio - jar 配置
第一项：
allprojects {
repositories {
google()
jcenter()
maven {
url 'https://jitpack.io' }
// 镜像 ：
// maven {
url 'https://maven.aliyun.com/repository/public' }
// maven {
url 'https://maven.aliyun.com/repository/central' }
}
第二项：config.gradle / build.gradle (app)
defaultConfig {
...
multiDexEnabled true
}
第三项：文档读取有JDK版本限制，最好是更新至1.8（异常崩溃点2）
android {
.......
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
三、权限配置
<!-- 外部存储 -->
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<!-- 管理外部存储 -->
<uses-permission
android:name="android.permission.MANAGE_EXTERNAL_STORAGE"
tools:ignore="ScopedStorage" />
异常点3： AndroidMainfest.xml 的 <application …
内添加 android:requestLegacyExternalStorage="true" 否则就会提示下列异常：
