以下是我使用库

的 xml文件

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#fff"
    tools:context="com.justswipe.document.MainActivity">

    <com.github.barteksc.pdfviewer.PDFView
        android:id="@+id/pdfView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginBottom="20dp" />

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerInParent="true"
        android:layout_margin="3dp"
        android:text="/" />
</RelativeLayout>

只有在我签署APK并将其安装在我的root手机的system / app文件夹中时才会出现错误。

如果没有签名，APK会正常运行。谁能帮忙..？我尝试过使用其他答案中给出的建议，似乎没有一个对我有用。
