How to get device (AOSP) Build Number in Android devices programmatically?

问题

From within an Android Application, how can the hosting device's Build Number, as displayed in System Settings -> About Tablet -> Build Number be obtained programmatically for use within a Java Android application?

Currently, I'm using "android.os.Build".

回答1:

Check this code..

in Build.FINGERPRINT you'll get the Build Number of the Device.

String mString = "";

    mString.concat("VERSION.RELEASE {" + Build.VERSION.RELEASE + "}");
    mString.concat("\nVERSION.INCREMENTAL {" + Build.VERSION.INCREMENTAL + "}");
    mString.concat("\nVERSION.SDK {" + Build.VERSION.SDK + "}");
    mString.concat("\nBOARD {" + Build.BOARD + "}");
    mString.concat("\nBRAND {" + Build.BRAND + "}");
    mString.concat("\nDEVICE {" + Build.DEVICE + "}");
    mString.concat("\nFINGERPRINT {" + Build.FINGERPRINT + "}");
    mString.concat("\nHOST {" + Build.HOST + "}");
    mString.concat("\nID {" + Build.ID + "}");

    ((TextView) findViewById(R.id.textView1)).setText(mString);

My Device Build Number :

FINGERPRINT return by the above code

To get only the Build Number value as shown on the "About Device" in settings, we can use the following static method:

/**
 * This method returns Build Number of the device from the OS Build fingerprint
 * @return osBuildNumber - human entered name of the device
 */
public static String getOSBuildNumber() {
    String osBuildNumber = Build.FINGERPRINT;  //"google/shamu/shamu:5.1.1/LMY48Y/2364368:user/release-keys”
    final String forwardSlash = "/";
    String osReleaseVersion = Build.VERSION.RELEASE + forwardSlash;
    try {
        osBuildNumber = osBuildNumber.substring(osBuildNumber.indexOf(osReleaseVersion));  //"5.1.1/LMY48Y/2364368:user/release-keys”
        osBuildNumber = osBuildNumber.replace(osReleaseVersion, "");  //"LMY48Y/2364368:user/release-keys”
        osBuildNumber = osBuildNumber.substring(0, osBuildNumber.indexOf(forwardSlash)); //"LMY48Y"
    } catch (Exception e) {
        Log.e("getOSBuildNumber", "Exception while parsing - " + e.getMessage());
    }

    return osBuildNumber;
}

This will just return the exact value of the build number. Please keep in mind that Android SDK refrains from doing this. Check the following snippet in BUILD class:

/** A string that uniquely identifies this build.  Do not attempt to parse this value. */
public static final String FINGERPRINT = deriveFingerprint();

/**
 * Some devices split the fingerprint components between multiple
 * partitions, so we might derive the fingerprint at runtime.
 */
private static String deriveFingerprint() {
    String finger = SystemProperties.get("ro.build.fingerprint");
    if (TextUtils.isEmpty(finger)) {
        finger = getString("ro.product.brand") + '/' +
                getString("ro.product.name") + '/' +
                getString("ro.product.device") + ':' +
                getString("ro.build.version.release") + '/' +
                getString("ro.build.id") + '/' +
                getString("ro.build.version.incremental") + ':' +
                getString("ro.build.type") + '/' +
                getString("ro.build.tags");
    }
    return finger;
}

The above method is just reverse engineering the data provided in the "deriveFingerprint()" method.

回答3:

To get this value, use Build.DISPLAY. Here is an example from Verizon Note 2 ( SCH-I605 on android 4.4.2) : KOT49H.I605VRUFND7

Requires : API 3 or higher.

回答4:

I hope it is return same value which you want..

String build_number = Build.FINGERPRINT;
System.out.println("Build Number" + build_number);

回答5:

I used String Build_Number = Build.DISPLAY; to get Build number as it shown at Phone settings

回答6:

Use Build.DISPLAY for Build Number

回答7:

Log.i("TAG", "SERIAL: " + Build.SERIAL);
Log.i("TAG","MODEL: " + Build.MODEL);
Log.i("TAG","ID: " + Build.ID);
Log.i("TAG","Manufacture: " + Build.MANUFACTURER);
Log.i("TAG","brand: " + Build.BRAND);
Log.i("TAG","type: " + Build.TYPE);
Log.i("TAG","user: " + Build.USER);
Log.i("TAG","BASE: " + Build.VERSION_CODES.BASE);
Log.i("TAG","INCREMENTAL " + Build.VERSION.INCREMENTAL);
Log.i("TAG","SDK  " + Build.VERSION.SDK);
Log.i("TAG","BOARD: " + Build.BOARD);
Log.i("TAG","BRAND " + Build.BRAND);
Log.i("TAG","HOST " + Build.HOST);
Log.i("TAG","FINGERPRINT: "+Build.FINGERPRINT);
Log.i("TAG","Version Code: " + Build.VERSION.RELEASE);

Ho it will work.
