Android 6.0 internal update apk parsing error

problem

Android 6.0 internal update function, when installing apk, there is an error in parsing data.

bug location

1. It is possible that the installation package has not been downloaded successfully, or the downloaded installation package is incomplete, this needs to be checked by yourself.
2. It is possible that you have written the installation package in cacheit, which leads to unsuccessful installation under Android 6.0.

solution

1. For the location of the first bug, check whether the apk is downloaded correctly;
2. For the location of the second bug, that is the issue of permissions. Code directly

 if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) {
                intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
                intent.setDataAndType(Uri.fromFile(newFile), "application/vnd.android.package-archive");
                chmod("777", newFile.getAbsolutePath());//apk放在cache文件中，需要获取读写权限
            } 

  /**
     * 
     * @param permission
     * @param path
     */
    public static   void chmod(String permission, String path) {
        try {
            String command = "chmod " + permission + " " + path;
            Runtime runtime = Runtime.getRuntime();
            runtime.exec(command);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
