我尝试以编程方式重启Galaxy S3。
我尝试过的事情:
try {
Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", "reboot" });
proc.waitFor();
} catch (Exception ex) {
Log.i("RebootActivity", "Could not reboot", ex);
}
try {
Runtime.getRuntime().exec(new String[]{"su","-c","reboot now"});
} catch (IOException e) {
e.printStackTrace();
}
try
{
Process process = Runtime.getRuntime().exec("su");
DataOutputStream os = new DataOutputStream(process.getOutputStream());
os.writeBytes("reboot now\n");
}
catch (Throwable t)
{
t.printStackTrace();
}
你们有任何想法如何实现这个目标吗?
感谢。

尝试做一个正常的字符串,看起来像“su \ n reboot; \ n“而不是数组。 尝试从shell中获得答案,这有助于调试。
你的su二进制文件有哪些权限?如果他们错了,你可以在“mount -o remount,rw / system”之后尝试“chmod 7777 / system / xbin / su”
下面是一些示例代码:(运行string命令,这是一个\ n和\或;分离的linux shell命令列表)
StringBuffer commandOutput = new StringBuffer();
try {
Process process = Runtime.getRuntime().exec("su\n");
DataOutputStream out = new DataOutputStream(process.getOutputStream());
out.writeBytes("export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/vendor/lib:/system/lib\n");
out.writeBytes(command+"\n");
out.flush();
process.waitFor();
BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream()));
int numRead;
char[] buffer = new char[1000];
while ((numRead = in.read(buffer)) > 0) {
commandOutput.append(buffer, 0, numRead);
}
in.close();
process.waitFor();
} catch ...
return commandOutput.toString();

您可以使用PowerManager
使其重新启动(这并不能保证它会重启 - 操作系统可能会取消它):
