android--app安装

app安装,在7.0后读取文件需要权限,没有添加权限会安装失败.

    /**
     * 安装apk
     */
    private void installAPK() {
        File file = new File(apkPath);
        Intent intent = new Intent();
        intent.setAction(Intent.ACTION_VIEW);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
        Uri data = Uri.fromFile(file);
        intent.setDataAndType(data, "application/vnd.android.package-archive");
        startActivity(intent);
    }
