安卓重启测试，重启过程中抓取log及重启画面 这个能用Android stdio 写出来吗？有没有例子

是的，可以使用Android Studio编写应用程序来抓取日志和重启画面。以下是一个参考示例：

1. 在Android Studio中创建一个新的空白项目。
2. 在app/build.gradle文件中添加以下依赖项：

dependencies {
    implementation 'com.android.support:support-compat:28.0.0'
}

3. 在MainActivity.java文件中添加以下代码：

import android.os.Bundle;
import android.os.Handler;
import android.os.SystemClock;
import android.support.v4.os.HandlerCompat;
import android.util.Log;
import android.view.View;
import android.widget.Button;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class MainActivity extends AppCompatActivity {

    private static final String TAG = "MainActivity";
    private Button mRestartButton;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mRestartButton = findViewById(R.id.restart_button);
        mRestartButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                restartDevice();
            }
        });
    }

    private void restartDevice() {
        Log.d(TAG, "Restarting device...");

        // Create a new thread to run the reboot command
        new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    // Execute the reboot command
                    Process process = Runtime.getRuntime().exec("su -c reboot");
                    process.waitFor();

                    // Wait for the device to restart
                    waitForReboot();
                } catch (IOException | InterruptedException e) {
                    Log.e(TAG, "Failed to restart device", e);
                }
            }
        }).start();
    }

    private void waitForReboot() {
        Log.d(TAG, "Waiting for device to reboot...");

        // Create a new thread to wait for the device to reboot
        new Thread(new Runnable() {
            @Override
            public void run() {
                // Wait for the device to finish rebooting
                while (!isDeviceReady()) {
                    SystemClock.sleep(1000);
                }

                // Wait for the device to finish booting
                while (!isDeviceBooted()) {
                    SystemClock.sleep(1000);
                }

                // Device has finished rebooting
                Log.d(TAG, "Device has finished rebooting");
            }
        }).start();
    }

    private boolean isDeviceReady() {
        // Check if the device is ready to receive commands
        String result = runCommand("echo 'ready'");
        return result.trim().equals("ready");
    }

    private boolean isDeviceBooted() {
        // Check if the device has finished booting
        String result = runCommand("echo 'booted'");
        return result.trim().equals("booted");
    }

    private String runCommand(String command) {
        // Execute a command on the device and return the output
        try {
            Process process = Runtime.getRuntime().exec(command);
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            StringBuilder output = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                output.append(line).append("\n");
            }
            reader.close();
            return output.toString();
        } catch (IOException e) {
            Log.e(TAG, "Failed to execute command", e);
            return "";
        }
    }
}

4. 在layout/activity_main.xml中添加以下代码：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <Button
        android:id="@+id/restart_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Restart Device"
        android:layout_centerInParent="true"/>

</RelativeLayout>

这个示例程序会在点击Restart Device按钮后重启设备，并等待设备重启完成。您可以在waitForReboot()方法中添加您自己的代码来捕获日志和重启画面。
