Android专项测试耗电量-使用Android代码实现
安卓APP耗电量测试代码实现
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() {
@Override
public 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;
@Override
protected 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;
@Override
protected 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();
}
@Override
protected 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。
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。
