安卓APP耗电量测试方案和源码，用Android代码实现
作为一名AI助手，我不会编写代码，但我可以为您提供一些关于安卓APP耗电量测试方案和源码的信息和建议。
安卓APP耗电量测试方案：
-
使用安卓系统自带的电池使用情况统计功能，查看应用程序的电池使用情况。
-
使用第三方电池测试应用程序，例如AccuBattery、GSam Battery Monitor等。
-
使用工具进行电池消耗测试，例如Battery Historian、Monsoon Power Monitor等。
安卓APP耗电量测试源码：
以下是一些参考源码，您可以根据需要进行修改和优化：
-
使用安卓系统电池使用情况统计功能：
BatteryManager bm = (BatteryManager) context.getSystemService(Context.BATTERY_SERVICE);
int batteryLevel = bm.getIntProperty(BatteryManager.BATTERY_PROPERTY_CAPACITY);
-
使用第三方电池测试应用程序：
IntentFilter ifilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
Intent batteryStatus = context.registerReceiver(null, ifilter);
int level = batteryStatus.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
int scale = batteryStatus.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
float batteryPct = level / (float)scale;
-
使用工具进行电池消耗测试：
private static final String TAG = "BatteryTest";
private static final int TEST_DURATION_SECONDS = 60;private PowerManager.WakeLock mWakeLock;
private BatteryManager mBatteryManager;
private Handler mHandler;
private Runnable mRunnable;
private boolean mTestRunning;
private int mStartLevel;
private int mEndLevel;
private int mBatteryDrain;private void startBatteryTest() {mTestRunning = true;mStartLevel = mBatteryManager.getIntProperty(BatteryManager.BATTERY_PROPERTY_CAPACITY);mWakeLock.acquire();mHandler.postDelayed(mRunnable, TEST_DURATION_SECONDS * 1000);
}private void endBatteryTest() {mTestRunning = false;mEndLevel = mBatteryManager.getIntProperty(BatteryManager.BATTERY_PROPERTY_CAPACITY);mBatteryDrain = mStartLevel - mEndLevel;mWakeLock.release();
}private void initBatteryTest() {mBatteryManager = (BatteryManager) getSystemService(BATTERY_SERVICE);mHandler = new Handler();mWakeLock = ((PowerManager) getSystemService(POWER_SERVICE)).newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, TAG);mRunnable = new Runnable() {@Overridepublic void run() {endBatteryTest();Log.i(TAG, "Battery drain: " + mBatteryDrain + "%");}};
}
以上是一些简单的安卓APP耗电量测试方案和源码，您可以根据需要进行修改和完善。同时，为了准确测试应用程序的耗电量，建议在测试时关闭其他应用程序和服务，以保证测试结果的准确性。
获取Android电池各项状态信息的实例
以下是获取 Android 电池各项状态信息的实例代码：
public class BatteryInfoActivity extends AppCompatActivity {private TextView mBatteryLevelTextView;private TextView mBatteryStatusTextView;private TextView mBatteryHealthTextView;private TextView mBatteryTechnologyTextView;private TextView mBatteryTemperatureTextView;private TextView mBatteryVoltageTextView;private TextView mBatteryPluggedTextView;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_battery_info);mBatteryLevelTextView = findViewById(R.id.battery_level_text_view);mBatteryStatusTextView = findViewById(R.id.battery_status_text_view);mBatteryHealthTextView = findViewById(R.id.battery_health_text_view);mBatteryTechnologyTextView = findViewById(R.id.battery_technology_text_view);mBatteryTemperatureTextView = findViewById(R.id.battery_temperature_text_view);mBatteryVoltageTextView = findViewById(R.id.battery_voltage_text_view);mBatteryPluggedTextView = findViewById(R.id.battery_plugged_text_view);IntentFilter intentFilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);Intent batteryStatusIntent = registerReceiver(null, intentFilter);if (batteryStatusIntent != null) {int level = batteryStatusIntent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);int scale = batteryStatusIntent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);float batteryLevel = level / (float) scale * 100;mBatteryLevelTextView.setText(getString(R.string.battery_level, batteryLevel));int status = batteryStatusIntent.getIntExtra(BatteryManager.EXTRA_STATUS, -1);String statusString = "";switch (status) {case BatteryManager.BATTERY_STATUS_CHARGING:statusString = "Charging";break;case BatteryManager.BATTERY_STATUS_DISCHARGING:statusString = "Discharging";break;case BatteryManager.BATTERY_STATUS_FULL:statusString = "Full";break;case BatteryManager.BATTERY_STATUS_NOT_CHARGING:statusString = "Not charging";break;case BatteryManager.BATTERY_STATUS_UNKNOWN:statusString = "Unknown";break;}mBatteryStatusTextView.setText(getString(R.string.battery_status, statusString));int health = batteryStatusIntent.getIntExtra(BatteryManager.EXTRA_HEALTH, -1);String healthString = "";switch (health) {case BatteryManager.BATTERY_HEALTH_COLD:healthString = "Cold";break;case BatteryManager.BATTERY_HEALTH_DEAD:healthString = "Dead";break;case BatteryManager.BATTERY_HEALTH_GOOD:healthString = "Good";break;case BatteryManager.BATTERY_HEALTH_OVERHEAT:healthString = "Overheat";break;case BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE:healthString = "Over voltage";break;case BatteryManager.BATTERY_HEALTH_UNKNOWN:healthString = "Unknown";break;case BatteryManager.BATTERY_HEALTH_UNSPECIFIED_FAILURE:healthString = "Unspecified failure";break;}mBatteryHealthTextView.setText(getString(R.string.battery_health, healthString));String technology = batteryStatusIntent.getStringExtra(BatteryManager.EXTRA_TECHNOLOGY);mBatteryTechnologyTextView.setText(getString(R.string.battery_technology, technology));int temperature = batteryStatusIntent.getIntExtra(BatteryManager.EXTRA_TEMPERATURE, -1);float temperatureCelsius = temperature / 10f;mBatteryTemperatureTextView.setText(getString(R.string.battery_temperature, temperatureCelsius));int voltage = batteryStatusIntent.getIntExtra(BatteryManager.EXTRA_VOLTAGE, -1);mBatteryVoltageTextView.setText(getString(R.string.battery_voltage, voltage));int plugged = batteryStatusIntent.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);String pluggedString = "";switch (plugged) {case BatteryManager.BATTERY_PLUGGED_AC:pluggedString = "AC";break;case BatteryManager.BATTERY_PLUGGED_USB:pluggedString = "USB";break;case BatteryManager.BATTERY_PLUGGED_WIRELESS:pluggedString = "Wireless";break;case 0:pluggedString = "Not plugged";break;}mBatteryPluggedTextView.setText(getString(R.string.battery_plugged, pluggedString));}}
}
上述代码中，我们通过 BatteryManager 类的常量和方法获取了电池的各项状态信息，例如电池电量、电池状态、电池健康状态、电池技术、电池温度、电池电压和电池充电状态等。同时，我们还通过 TextView 控件将这些状态信息展示在了界面上。
注意，获取电池状态信息需要监听 Intent.ACTION_BATTERY_CHANGED 广播，因此我们在 onCreate() 方法中注册了该广播。此外，在获取电池电量时，我们需要先获取当前电量和最大电量，再计算出电池电量百分比。
统计Android APP耗电量（mah）的实例
要统计 Android APP 的耗电量，可以使用 BatteryManager 类提供的方法来获取电量信息，并在 APP 启动和关闭时记录电量信息。然后在 APP 关闭时计算电量差，即可得到 APP 的耗电量。
以下是一个简单的实现示例：
public class MainActivity extends AppCompatActivity {private BatteryManager mBatteryManager;private int mStartBatteryLevel;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);// 获取 BatteryManager 实例mBatteryManager = (BatteryManager) getSystemService(BATTERY_SERVICE);// 记录 APP 启动时的电量mStartBatteryLevel = getBatteryLevel();}@Overrideprotected void onDestroy() {super.onDestroy();// 计算 APP 的耗电量int endBatteryLevel = getBatteryLevel();int batteryConsumed = mStartBatteryLevel - endBatteryLevel;Log.d("Battery", "APP consumed " + batteryConsumed + " mAh");}/*** 获取当前电量*/private int getBatteryLevel() {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {BatteryManager batteryManager = (BatteryManager) getSystemService(BATTERY_SERVICE);return batteryManager.getIntProperty(BatteryManager.BATTERY_PROPERTY_CAPACITY);} else {Intent intent = registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));int level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);return (int) (level / (float) scale * 100);}}
}
在 onCreate() 方法中记录 APP 启动时的电量，onDestroy() 方法中计算 APP 的耗电量。getBatteryLevel() 方法用于获取当前电量，根据 Android 版本的不同，使用不同的方式获取电量信息。
注意，该示例只能得到 APP 的近似耗电量，因为在 APP 运行期间，电池电量可能会因为其他应用程序或系统服务的影响而发生变化。
