How do I get the temperature of the battery in android? Ingo Try this: private class mBatInfoReceiver extends BroadcastReceiver{ int temp = 0; float get_temp(){ return (float)(temp / 10); } @Override public void onReceive(Context arg0, Intent intent) { temp = intent.getIntExtra(BatteryManager.EXTRA_TEMPERATURE,0); } }; then define in your Variable declarations: private mBatInfoReceiver myBatInfoReceiver; and in onCreate: @Override public void onCreate(Bundle b) { super.onCreate(b); setContentView(R.layout.activity_main); // ... // Add this myBatInfoReceiver = new mBatInfoReceiver(); this

When you use TYPE_MAGNETOMETER sensor, you get X, Y, Z values of magnetic field strength in relation to the device orientation. What I want to get is to convert these values into global reference frame, clarifying: user takes the device, measure these values, than rotate the device for some degrees around any axis and gets ~the same values. Please, find similar questions below: Getting magnetic field values in global coordinates How can I get the magnetic field vector, independent of the device rotation? In this answer sample solution is described (it is for linear acceleration, but I think it

I am just a beginner in the application development industry. I know the accelerometer can be used to return the current acceleration along three axis in meters per second squared (m/s2). But I have come to know that an accelerometer can also be use as speedometer. I want to know how I can use accelerometer to determine distance traveled by Android device between points of interest. If it is possible, then how can I implement it? I have seen a similar question "how do I measure the distance traveled by an Iphone using accelerometer" How do I measure the distance traveled by an iPhone using the
