Android修改默认浏览器为其他浏览器(UC)

public class MainActivity extends Activity {

private static final String TAG = "MainActivity";

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

PackageManager packageManager = this.getPackageManager();

String str1 = "android.intent.category.DEFAULT";

String str2 = "android.intent.category.BROWSABLE";

String str3 = "android.intent.action.VIEW";

// 设置默认项的必须参数之一,用户的操作符合该过滤器时,默认设置起效

IntentFilter filter = new IntentFilter(str3);

filter.addCategory(str1);

filter.addCategory(str2);

filter.addDataScheme("http");

// 设置浏览页面用的Activity

ComponentName component = new ComponentName("com.UCMobile",

"com.UCMobile.main.UCMobile");

Intent intent = new Intent(str3);

intent.addCategory(str2);

intent.addCategory(str1);

Uri uri = Uri.parse("http://");

intent.setDataAndType(uri, null);

// 找出手机当前安装的所有浏览器程序

List resolveInfoList = packageManager

.queryIntentActivities(intent,

PackageManager.GET_INTENT_FILTERS);

int size = resolveInfoList.size();

ComponentName[] arrayOfComponentName = new ComponentName[size];

for (int i = 0; i < size; i++) {

ActivityInfo activityInfo = resolveInfoList.get(i).activityInfo;

String packageName = activityInfo.packageName;

String className = activityInfo.name;

Log.d(TAG, "packageName  " + packageName);

Log.d(TAG, "className  " + className);

// 清除之前的默认设置

packageManager.clearPackagePreferredActivities(packageName);

ComponentName componentName = new ComponentName(packageName,

className);

arrayOfComponentName[i] = componentName;

}

packageManager.addPreferredActivity(filter,

IntentFilter.MATCH_CATEGORY_SCHEME, arrayOfComponentName,

component);

}

记得 及系统签名噢
