android 执行shell命令代码

android 执行shell命令方法

可执行su、sh命令 只需传入需要执行的命令即可进行执行

如：执行安装apk包命令：

new ShellCommand().sh.runWaitFor("pm install -r " + /.../apkName.apk)

import java.io.DataInputStream;

import java.io.DataOutputStream;

import java.io.InputStream;

import android.util.Log;

public class ShellCommand {

private Boolean can_su;

public SH sh = new SH("sh");

public SH su = new SH("su");

public boolean canSU(){

return canSU(false);

}

public boolean canSU(boolean paramBoolean){

if ((this.can_su == null) || (paramBoolean)){

CommandResult localCommandResult = this.su.runWaitFor("id");

StringBuilder localStringBuilder = new StringBuilder();

if (localCommandResult.stdout != null){

localStringBuilder.append(localCommandResult.stdout).append(" ; ");

}

if (localCommandResult.stderr != null){

localStringBuilder.append(localCommandResult.stderr);

}

Log.v("ShellCommand.java", "canSU() su[" + localCommandResult.exit_value + "]: " + localStringBuilder);

this.can_su = Boolean.valueOf(localCommandResult.success());

}

return this.can_su.booleanValue();

}

public SH suOrSH(){

SH localSH;

if(!canSU()){

localSH = this.sh;

}else{

localSH = this.su;

}

return localSH;

}

public class CommandResult{

public final Integer exit_value;

public final String stderr;

public final String stdout;

public CommandResult(Integer paramString1, String paramString2, String arg4){

this.exit_value = paramString1;

this.stdout = paramString2;

this.stderr = arg4;

}

public boolean success(){

int i = 1;

if ((this.exit_value == null) || (this.exit_value.intValue() != 0)){

i = 0;

}

return i==1?true:false;

}

}

public class SH{

private String SHELL = "sh";

public SH(String arg2){

this.SHELL = arg2;

}

private String getStreamLines(InputStream paramInputStream){

}else{

}

}

}catch (Exception e){

}catch (InterruptedException localInterruptedException){

}catch (NullPointerException localNullPointerException){
