  • Android android.os.FileUriExposedException: exposed beyond app through Intent.getData()错误

    1、在AndroidManifest.xml中添加如下代码

     <application
            android:name="com.rfid.application.MyApplication"
            android:allowBackup="true"
            android:icon="@drawable/ic_launcher"
            android:label="@string/app_name"
            android:roundIcon="@mipmap/ic_launcher_round"
            android:supportsRtl="true"
            android:usesCleartextTraffic="true"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
    
          
            <provider
                android:name="androidx.core.content.FileProvider"
                android:authorities="com.rfid.application.MyApplication.provider"
                android:exported="false"
                android:grantUriPermissions="true">
                <meta-data
                    android:name="android.support.FILE_PROVIDER_PATHS"
                    android:resource="@xml/provider_paths"/>
            </provider>
    
    
        </application>

    2、在res目录下新建一个xml文件夹,并且新建一个provider_paths的xml文件

    <?xml version="1.0" encoding="utf-8"?>
    <paths xmlns:android="http://schemas.android.com/apk/res/android">
        <external-path name="external_files" path="."/>
    </paths>

    3、修改代码

           File apkFile = new File(saveFileName);
               if (!apkFile.exists()) {
                   return;
               }
               
               Intent intent = new Intent(Intent.ACTION_VIEW);
               
               if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N){
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); Uri contentUri
    = FileProvider.getUriForFile(mContext, "com.rfid.application.MyApplication.provider", apkFile); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); intent.setDataAndType(contentUri, "application/vnd.android.package-archive");
    }
    else{ intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.setDataAndType(Uri.fromFile(apkFile), "application/vnd.android.package-archive"); } mContext.startActivity(intent);
