文件管理器获取root权限后，注意获取成功！到真机上上测试也是提示获取权限成功，可是问题来了为啥这还访问不了/root等文件夹呢
权限获取代码：
- Java code
/** * 应用程序运行命令获取 Root权限，设备必须已破解(获得ROOT权限) * * @param command * 命令：String apkRoot="chmod 777 "+getPackageCodePath();//RootCommand(apkRoot); * @return 应用程序是/否获取Root权限 */ public static boolean RootCommand(String command) { Process process = null; DataOutputStream os = null; try { process = Runtime.getRuntime().exec("su"); os = new DataOutputStream(process.getOutputStream()); os.writeBytes(command + "\n"); os.writeBytes("exit\n"); os.flush(); process.waitFor(); } catch (Exception e) { return false; } finally { try { if (os != null) { os.close(); } process.destroy(); } catch (Exception e) { } } return true; }------解决方案--------------------
Process process = null;
DataOutputStream os = null;
try {String command = "chmod 777 " + "data";
process = Runtime.getRuntime().exec("su");
os = new DataOutputStream(process.getOutputStream());
os.writeBytes(command + "\n");
os.writeBytes("exit\n");
os.flush();
process.waitFor();
} catch (Exception e) {
} finally {
try {
if (os != null) {
os.close();
}
process.destroy();
} catch (Exception e) {
}
}
这样可以访问data文件夹
------解决方案--------------------
String[] command={"su","-c","/data"}
Process=Runtime.getRuntime().exec(command);
process.waitfor();
os = new DataOutputStream(process.getOutputStream());
不知道这样行不行了~
